Logitech MX Mechanical Keyboard and MX Master 3S Mouse Review















A few weeks ago, Logitech quietly dropped two new MX peripherals. The first one is the new MX Master 3S mouse, the successor to the famous Master 3. I’ll review this a little later in the review, but the new kid on the block is the new MX mechanical keyboard, specifically a low-profile mechanical keyboard.

This new series fuses the slim form factor we all love and appreciate with the best Logitech gaming keyboard expertise. Remember the MX keys and the G9 15 series launched a while ago? Essentially carried over some of the characteristics from the gaming line-up, like the switches and the slim nature.

Plus, all the productivity features of the MX keys to give to the mechanical series, and I’ve been using it for the past few weeks. And let me tell you, this period with the new 3S mouse is the perfect master combo. Of course, this mouse works, but I’ll discuss that later in the review.

So, stick around for that. Now Logitech offers the keyboard in two form factors. The standard full-size setup will cost you $170, and the mini version is $20 cheaper. They also come in three switch types: tactile, clicky and linear.

Frequently Asked Questions for MX Mechanical Keyboard

Is it possible to swap out the switches with other low-profile models?

For example, you can replace hot-swappable keycaps, but not switches.

Is it possible to pair the MX Master 3 mouse with this keyboard USB dongle? Maybe both dongles are needed.

You can’t use a mechanical keyboard dongle like the MX mechanical keyboard with the Master 3 because it comes with a logi bolt receiver, which is incompatible with Master 3.

For Linux key mapping, does it saved if I boot into Windows/Mac and use Logitech software to set custom key mappings?

For the customizations to work, you must have the Options+ software installed on your computer. Unfortunately, only Windows and Mac OS X are supported by Options+.

Is there a way to change the backlight’s timeout? On prior MX keyboards, this was not possible.

Whenever you return to your keyboard, the Logitech MX Mechanical Keyboard has a proximity sensor that identifies your hands. The only thing that can affect the brightness of the backlight is the sensor, and there is no way to alter that.

How long is the warranty period for this product?

The MX Mechanical Keyboard comes with a one-year limited hardware warranty.

When using the bolt receiver, what is the polling rate?

Bluetooth and the bolt receiver both have a polling rate of 8 milliseconds.

What are the specs for the switches?

The MX Mechanical and MX Mechanical Mini’s key switches have a total travel distance of 3.2 millimetres and an actuation distance of 1.3 micrometres.

Is there a way to modify the colour of the LED?

No, you cannot change the color of the LED; however, you can alter the colour pattern.

Is it possible to use it as a wired keyboard when I’m in a situation where I can’t utilize the wifi or Bluetooth option?

Due to the fact that the USB cable is used only for charging the device, you cannot utilize the wired mode of the Logitech MX Mechanical Keyboard. You must connect the mouse using the Wifi or Bluetooth device for it to work.

Built Quality of MX Mechanical Keyboard

But for now, I’m going to kick things off with the build quality of the MX mechanical. The whole chassis is constructed out of post-consumer recycled plastic materials, which helps with the sustainability factor and the keyboard’s overall weight. It still feels super sturdy with the aluminium top case since there were no signs of quaking, plus the switches don’t rattle when you shake it around.

Color and Design of MX Mechanical Keyboard

So huge props to Logitech for that, and I really liked the design of this keyboard instead of an all-black and boring colour theme. They actually changed it up by giving it a dual-tone, light and dark gray finish throughout the whole chassis and the key camps.

Of course, it’s a subtle contrast that blends in really well within any workspace. However, I wish that Logitech offers an all-white or pale Gray model to match the electronics setup I have on my workstation, but you can pick up the graphite color option to fit the whole setup. If you plan to pick up this combo for angle adjustments, the MX mechanical only offers a single-step eight-degree tilt option, which is perfect for my comfort level.

Accessibility, Charging and Backlight

The power switch is easily accessible at the top right-hand corner, and you can charge up the keyboard view USB type C. Since this is a wireless keyboard, there’s a battery status led indicator, which also functions as an ambient light sensor to trigger the keyboards smart illumination.

For starters, the sensor detects when your hand is approaching the keyboard and illuminates the keys. It’s a compelling feature that also helps extend battery life. This technology actually debuted a while ago on their ridiculously expensive Kraft keyboard. But this time, they’ve added some lighting effects like breathing and contrast, highlighting decontrol keys around the corner.

The led backlight is very bright. I had no issues distinguishing the keys at night, and it’s also visible during the daytime. So that’s great. Now, does this have RGB? No, but you shouldn’t be asking that question in the first place because this is a productivity keyboard and not a gaming type. So please, please keep that in mind.

Keycaps of MX Mechanical Keyboard

The key caps are nothing special. They are your basic abs plastic materials. I appreciate cross-platform awareness by including the start option and command all to combo keys for that seamless switch between Mac iOS and Windows. A lot of keyboard manufacturers have that, especially on the productivity side.

As someone who constantly switches between both of those platforms, let’s talk about these switches because, as I mentioned earlier, Logitech teamed up with kale to offer three different types of switches.

So there’s tactile (quiet-typing), linear(smooth-typing), and clicky (satisfying click).

I’ve been using the linear switches as my daily drivers since I prefer the uninterrupted key travel characteristics and minimal spring rebound. In addition, the MX Mechanical Keyboard linear switch is an excellent option for those who prefer a smooth bottoming-out experience and minimal actuation force.

Coming from Gator on reds, on the Keychron K1 that I use in my office. This Logitech MX Mechanical Keyboard was an easy transition for me, and I absolutely loved writing out scripts and doing general productivity tasks. The tactile option, according to Logitech, is their quieter said, but from switching between this and the linear.

I actually from the linear model to be a bit quieter than the tactile one since they are based on the kale brown switches. Although there is a slight tactile bump when you actuate the keys, which sharpens the feedback, it’s still an excellent option for those who prefer a smooth and clicky typing experience.

The clicky version doesn’t need all that explanation, guys, because if we’re looking for that beautiful audible, tactile experience, this is your only option. Personally, it’s a bit too loud for my taste, and I would highly recommend steering away from this option if you choose to pick this up for your workplace, where you share spaces.

Your co-workers might get really annoyed. Every actuation is well-defined, and you can instantly feel the reset point. You could consider this clicky version if you want to use it for some light gaming at home.

Wireless Performance

The wireless performance on the MX Mechanical Keyboard is incredible. If you’re looking for that clean, cable-free and subtle experience, this is probably the best option other than the MX keys. I had no issues with latency performance. These keyboards now use Logitech’s new bolt receiver, their next-generation wireless technology.

It essentially specializes in advanced security and robust connections, especially if you’re working in an environment where there are countless wireless devices. So, you don’t have to worry about interruptions when using it. You can also pair up to six-bolt compatible devices using a single receiver.

So, we have a lot of USB ports. I’ve been using the MX Mechanical Keyboard with the Master 3S mouse, and I’ve had zero interruptions in terms of connectivity aside from a few hiccups with this mouse. But I’ll talk about that a little bit later. Do remember that if you have a unifying receiver, you will not be able to pair that with the MX mechanical keyboard, so that kind of sucks.

You can also pair the keyboard to your computer via Bluetooth to pair the keyboard to another device or up to three, according to Logitech. This feature can come in a clutch. However, I think what really ties this whole experience is excellent cross-platform compatibility, along with their super simple options.

Plus, software, the easy switch feature on the keyboard, integrated with the F1 two and three keys on the mini or dedicated buttons on the full-size version. Essentially, the feature allows you to switch between devices seamlessly and instantly. For example, this keyboard is paired with a MacBook Pro and my desktop at home.

So just switching from one connects to my Mac book pro, and then if I hop on to two, it automatically switches to my PC, and it’s so instant. I don’t have to worry about constantly replunging things. So, it’s super convenient and swift. I love that whole switch process.

Logitech MX Mechanical Keyboard Software

If you take a look at the driver’s software, it’s straightforward. As I mentioned, the home screen gives you a bird’s-eye view of the peripherals connected. I have the 3S mouse paired as well, but if we look at the MX Mechanical Mini, you can customize the top row starting with F4 all the way to page down to any command.

With the full-sized version, you can access even more keys for customization with the entire function row and the four custom buttons on the white hand corner and editing and navigation keys over there. There’s a load of options that Logitech built already.

Logitech MX Mechanical Keyboard Battery

Now, the last thing I will cover here is battery life. The full size and the mini model feature the same 1500 million power battery. According to Logitech, they’re supposed to last up to 15 days with intelligent illumination enabled or up to 10 days.

That number sounds about right throughout my usage over the past few weeks. You could probably get a few more days’ worth of use out of this MX keyboard. If you plug the MX Mechanical Keyboard in for 15 minutes, you can get a full day’s worth of use.

So, I would say that’s a healthy number, but I’m a bit confused as to why Logitech didn’t include a bigger battery on the full-size version because, as you can see, there’s more room on the keyboard. It’s a lot bigger than the mini. So, I think this is a missed opportunity considering the extra $20 premium you are paying over the MX mechanical mini.

MX Master 3S Mouse Review

I’m going to switch gears and talk about the MX Master 3S mouse. They’ve actually still managed to keep it at that $99 price point, which is fantastic, but it is still an expensive investment. However, with constant sales going around on Amazon and Best Buy, you could potentially pick this up for a lower price point.

Color Options and Sound

So, what’s new with the MX Master 3S mouse? Well, honestly, there’s not much to talk about other than the fact that it comes in the new pale gray finish, which is technically white, and it’s a refreshing look for the MX line-up. You can also pick it up in black and the usual graphite option. They’ve also upgraded the switches to yield a quieter experience than the previous model.

Sensor Performance

The other upgrade is with the sensors. So would be MX Master 3 mouse, the DPI was capped at 4,000, but with MX Master 3S mouse, you can now go up to 8,000 DPI. I would have never utilized this feature unless I had an insanely high-resolution monitor or multiple monitors stacked. Still, it is a fantastic sensor for my everyday usage, which primarily involves video editing, making thumbnails using Photoshop and doing my research for videos.

The Shape of the MX Master 3S Mouse

I still love the shape of this mouse very much. It’s perfect for my large hands since they can comfortably wrap around the body for a Palm style grip. Unfortunately, Logitech doesn’t make a version for left-hand users, which is a missed opportunity to include that option.

But if you’re looking for something ambidextrous, the MX Anywhere 3 is an alternative option that’s also cheaper.

The max speed scroll wheel is still one of the best features you can ask for in a productivity focus mouse. If you’re a programmer scrolling through lines of code, or someone working with Excel, just scrolling through tons and tons of data sheets, or even browsing the web.

Features of MX Master 3S Mouse

The Master 3 mouse is a complete game changer and is just one of the best mouse I’ve tried so far. Also, the wheel on the right-hand side of the one on the side makes the experience even better because you can now switch tabs between Chrome or Safari or use it to horizontally shift the timeline or even change the brush size within Photoshop.

Now, oddly for some. That feature didn’t work with Photoshop on my Mac Pro, but I had no issues using it on my surface pro eight; perhaps this is a compatibility issue with apple Silicon. I’ve reached out to Logitech, and I’m still waiting for a response from their technical team.

Connectivity Issue of MX Master 3S Mouse

So I’ll pin any updates that I get down below. I want to pause here and address the elephant in the room, which is the connectivity issues that some folks have been experiencing with the MX Master 3S Mouse. With Bluetooth, things that have to do with sleep, wake, cursor, lag, or jitteriness or whatever you want to call it and some of the software glitches that I talked about earlier, my surface pro eight paired with the 3S via Bluetooth with no problem. But weirdly, the Logitech Option+ couldn’t pick up the mouse. So, I couldn’t customize the buttons specifically for that device. So, I had to switch to the bolt receiver.

I’ve been using the Master 3 since launch, and I’ve never had any issues with connectivity. So, experiencing this issue on the newer model was a bit of a red flag. The bottom line is if you’re on windows, you shouldn’t have any problems using the bold receiver, but if you’re on apple Silicon like I am, then you’re not going to be able to take full advantage of the MX Master 3S Mouse.

When it works, it’s fantastic, and you can fine-tune the mouse using the options plus software. For instance, you can use the gesture button to control or launch mission control for MacOS. In Windows, you can enable Windows navigation by holding the button down and moving left or suitable switches between desktops; holding it and moving up or down can increase or decrease the volume.

Seriously. I can spend an hour walking you through all the functions that can be mapped to all of these buttons. The fact that Logitech is giving us these options is a testament to why the MX series is still one of the best productivity mice you can buy.

Battery Life for MX Master 3S Mouse

Battery life is about the same on the Master 3 mouse, where you still get about 70 days’ worth of use on a full charge, and it tops the battery over USB-C. You can get about three hours of service from just a minute of charging. I expected an upgrade in the battery for this newer model. But like I mentioned earlier, not much has changed between the Master 3 and the MX Master 3S Mouse.

My Verdict on Logitech MX Mechanical Keyboard and MX Master 3S Mouse

Suppose you’re looking for the ultimate wireless freedom with features that enhance your productivity and a little more character with the low-profile mechanical switches. In that case, Logitech MX Mechanical Keyboard should be on the top of your list. Unfortunately, the keyboard is priced at $170 for the full-sized version and $150 for the mini. It’s a lot of money. Are there any cheaper wireless low-profile mechanical alternatives out there?

Absolutely, but I think you’re paying for the robust software customization and seamless transition between different platforms and as someone who lives on an everyday basis. I’m in love with the mechanical mini version, which I’m sticking to for the long term.

But if you’re still on the fence about this keyboard, consider looking at the MX Keys, it’s a lot cheaper than the MX Mechanical, and it’s still a fantastic option for productivity. You don’t get that clickety-clack experience.

Next is the MX Master 3S Mouse. But, again, I find absolutely no reason to get MX Master 3S Mouse over the Master 3, to be honest, unless you desperately need those quieter switches or the 8,000 DPI sensor. But, of course, by now, you might be able to pick up the master three for a good deal because you’re essentially getting 95% or almost 99% of the MX Master 3S Mouse. And, of course, you don’t have to worry about the connectivity issues some folks have been experiencing.

Thank you for reading my Logitech MX Mechanical Keyboard and MX Master 3S Mouse review. I hope you can take away everything you needed to know about the MX mechanical series and the new Logitech MX Master 3S Mouse from Logitech.
