 Oh, hold it. Run that back. Sector G6 there, zoom in. Whoa, there. Freeze that. What is it? Enhance. Enhance. Look at his wrist. Nobody walks with their arms pronated like that. It's ergonomics 101, Jim. My god. If we can get an ergonomic Logitech vertical mouse to him, he might just have a fighting chance before he... Before what? Well, before he develops a repetitive strain injury and gets fired. Logitech's MX series of flagship mice, including the full-featured MX Master 2S, travel-friendly MX Anywhere 2S, and MX Ergo for trackball enthusiasts, now has a new addition to the mischief that... the mischief? Really? A group of mice is called a mischief? Well, you learn something every day. Okay, anyway, it's the MX Vertical, Logitech's first vertical mouse. Now, the idea behind vertical mice, which have been around for an eye on 20 years now, is to maximize comfort and avoid carpal tunnel syndrome and other repetitive strain injuries that can be caused by lying your hand flat for long periods of time. This is known as pronation and actually causes your two forearm bones, the radius and the ulna, to scissor, which can pinch the tissue inside the forearm, increasing pressure in the carpal tunnel. It can also inflame tendons. So, yes, that's right, folks. Going prone sometimes hurts more than it helps. Now, the MX Vertical's design mitigates this by putting your hand in more of a natural handshake position of 57 degrees, which is higher than the MX Ergo's optional tilt, but still less than the 90 degrees, which in theory would give you enhanced unscissoring, but then would also introduce new problems because instead of driving mouse clicks down towards the desk, they'd be going sideways where there's nothing to push against, so you just push your mouse away. I mean, you'd probably end up with an injury from squeezing the mouse constantly to try to hold it still instead of being able to relax, which is what the vertical's angle and wide thumb pad do allow for. Okay, so your arm bones are aligned and all that, but what is this thing like to use? Honestly, quite a bit weirder than I thought, and there's definitely a bit of a learning curve before you can point with the degree of accuracy that you're probably used to because you have to learn to move your arm on a totally different axis. Now, on a normal mouse, most of us execute big movements by pivoting from the elbow or from the shoulder and then fine movements by moving the wrist sideways a little bit like this, but while this does offer a lot of precision, it's actually an unhealthy movement with another fancy name, ulnar deviation, but with the vertical you actually do your fine movements like this, which becomes second nature after a week or two except for an unexpected problem that James, who I immediately unloaded this thing to when it arrived, ran into, which was a frustrating increase in what we're calling fake clicks, where you go to click on something and nothing happens, causing you to have to click again. So it took me a couple of goes to figure out why it wasn't registering sometimes, and it turns out that whether it's some combination of the vertical position or maybe the difference in fine motor control between moving your hand like this versus like this, but basically what's going on is that it's really easy to inadvertently click before you've actually stopped moving the mouse, and if you look closely you can actually see that the mouse is basically registering a tiny micro drag instead of a discrete click. Now it's possible that the main factor in all this is just that we have so much practice using horizontal like regular mice and that this could be a complete non-issue over time, or it's possible that you don't experience this issue at all and it's just a James thing, but all we can do is tell you our experiences and this is what I experienced, so there it is. One thing we expect to be agreeable to everyone though is the MX verticals looks. Despite Logitech's obvious focus on ergonomics, the mouse itself still manages to look frankly like a work of art. It looks like a seashell or a sailboat or like a sick jump, but even seemingly design-focused decisions here often have practical elements to them, so the soft touch rubber top for example is accented with these vertical ribs that play with the light more than the graphite color otherwise would, but also give it a pleasing grippy texture in the hand so you can't accidentally slip. Unfortunately this mouse doesn't exist in a vacuum and comparison is the thief of joy, so when we bring other mice into the picture the MX vertical loses some of its luster. Even though the MX vertical is lightweight and advertised as having the elevated performance of the MX series and even though it has forward and back buttons, a DPI selector that goes up to 4,000 DPI and left and right buttons that are rated to 10 million clicks, it still feels like it got a little shafted in terms of features compared to its siblings. So despite demanding the same 99 US dollar price the vertical has the fewest programmable buttons, it lacks a horizontal scroll wheel and gesture control and dark field tracking for use on highly reflective surfaces and while I understand that the angle of the mouse might have restricted Logitech from putting one of their awesome hyper scrolling wheels on here, I feel like at least a tilt wheel probably wasn't too much to ask. Honestly other than ergonomics the only thing about this mouse that makes it stand out against the others in the lineup is the fact that it uses USB type C, so you get the reversibility and the improvements to durability, not to mention that it will be handy to be able to use the same cable to charge your laptop, your Android phone and your mouse, but James and I actually had a pretty good debate about this when we were going through this, you could make the argument that some of those missing features that we mentioned before would be more important to many users than the type of USB port. In spite of all of that criticism though I can't think of any reason to hate this mouse, even if it was clearly built for folks with medium to large hands. The forward button is a bit of a top shelf in the kitchen kind of experience for a smaller person like me. It is expensive but it's a high quality right-handed mouse with modern Logitech benefits like dual connectivity via radio and Bluetooth, flow across multiple machines and this neat graphical DPI selector which unfortunately didn't work until I installed Logitech's options software. So if you're looking for a vertical mouse to help you prevent or recover from a repetitive strain injury and you don't mind spending three to five times as much as the competitive offerings in exchange for the Logitech pedigree then we can easily recommend it. Just don't try to game with it because it gets pretty warm actually. All that surface area.
