Ergodriven Om Handshake Vertical Mouse | Wireless Ergonomic Mouse | Rechargeable | Silent Click Micro-Force Switches | OLED Screen | Reduces Tension and Fatigue | Compatible with PC and Mac

Why I got this mouse: I got an ergo mouse because I noticed my hand's natural grip on my mouse made it so if I try to push my mouse directly up by just extending my arm, it goes diagonally to the right as I hold it at an angle (and my middle mouse was broken) Pros: Customizing the buttons is incredibly easy. No bloated software that requires startup permissions, just pure engineering and firmware on the mouse itself. This is impressive from a company that makes standing mats. It would still be impressive if a major mouse manufacturer made this. The far-back left and right click buttons are not easy to accidentally hit, meaning they can comfortably be used for audio player controls. The silent clicks on the main left and right click buttons are very satisfying and yet they still have enough feedback to know when you've clicked. It is *impossible* to hear the clicks unless your head is right next to the mouse. The same cannot be said about side buttons or the far-back ones though. OLED screen is high quality, which kinda encourages me to try getting a custom image on it for the lulz Cons: The manual is a QR code, and the mouse did not come with a charging cable. It also seems to encourage moving the mouse with the wrist more than the fingers, which could somewhat harm gaming performance until you adjust The mouse turns off from inactivity to save on power, and requires you to press any button to wake it up. This is annoying considering I went from a wired mouse to this The sensor is not ultra high spec, which means it's power-efficient, but they could probably squeeze out more power by using an e-ink screen (and it would not require the screen to be turned off to save battery, as e-ink stores its state without using any power) rather than oled since it doesn't need high refresh rate It's pretty heavy for a mouse, and it is bottom-heavy

Shockingly good ergonomic, vertical mouse, wireless (2.4 or BT) at this price point. My hand is about 7.25" from index finger to wrist / the end of my 'thumb pad', and this is easily the most comfortable mouse grip I've ever had. Compared to every other such mouse at a similar price range, you're getting two additional main left/right buttons, which contrary to what you may think, at least what I thought, you do not end up accidentally clicking. The way the grip works just makes that not happen. Oh, and those two extra buttons are macro customizable. I've set up one of mine to bind to a screen zoom function on my OS, just as an example. You've also got 3 thumb buttons, not the more standard 2... those can all be macro reassigned as well, and doing the reassignment doesn't require any software on your PC, its entirely contained within the mouse itself. Criticisms? Add a simple image or two that explains how to adjust the custom button macros/bindings to either your webpage or the store listing here on Amazon, or the little instruction placard that comes in the box. Mildly annoying to have to watch an unlisted youtube video for that information. But that's not really a problem with the mouse itself. Overall? Affordable, practical, best feature set out of comparable mice in this price tier. I'm honestly kind of shocked this thing is not super popular, you don't need to have carpal tunnel to appreciate this thing, its a little weird at first, but it makes so much more sense than a traditional mouse after maybe a day or less of use. I actually hope that one day there will be a 'premium' version of this mouse with a higher polling rate... of course that would make such a mouse cost more, and its current polling rate is more than fine for general productivity/office use, but I'd encourage Ergodriven to make basically a 'gamer' or 'premium' version of this same mouse, pop a fancier PixArt chip in there, and ya'll could maybe grab a share of the aging Millenial/Gen X PC Gamer cohort, hah! If you really wanna go into actual design refinements/changes maybe look into different kinds of modular, attachable/detachable grip pads for where your thumb and pointer finger grip, maybe also the pinky finger area? But the actual shape of the thing as it is... is just stellar, at least for myself, so don't change it too much!

ALMOST the perfect mouse for me. The big downside for me is it's size. The mouse itself is amazing, great connection, great battery life, the keybindings are easy to remap although I wish there was software to provide more easy customization. The amount of buttons provided allow a lot of functionality, and surprisingly enough I was actually using this for keybindings in video games instead of editing software or computer commands. As stated above I wish there were more built-in keybindings or perhaps software that would allow programs to recognize extra mouse buttons beyond 4 & 5. On to the size; I don't have particularly large hands, but I think if you intend to use a vertical mouse for long periods of time having a bigger mouse to grip helps the wrist. I have never experienced wrist pain with my larger vertical mouse but unfortunately I noticed wrist pain from prolonged use of this mouse, which I assume is due to it's smaller size and slightly different angle. Unfortunately due to this wrist pain I'll have to return the mouse, which I really wish I didn't have to do. Hopefully they release a larger model in the future, I'll be keeping an eye out. All that being said, Give it a try! This mouse is well worth the price, well made, feels good in the hand and provides a lot of useful buttons.

It’s fantastic piece of work. Silent click is a bonus. Does its job.
