Evoluent Vertical Mouse V4 Right

It is very useful for healing wrist pain due to extended use of mouse.. I would recommend it to everyone using the mouse for long duration ..

On day 1 it was working fine but after a week mouse itselfnot getting connected for use. Worst product

I had painful carpal tunnel syndrome, which worried me because as a software engineer, I'm expected to use a computer all day for my living. Using this mouse plus Apple's Magic Trackpad cured the carpal tunnel syndrome. I can now put in a full day's work without any hand pain. The first thing I noticed when I started using this is that my wrist is in its natural position (handshake position), rather than rotated 90 degrees to use a conventional mouse. I use the wired version of this mouse. The cable is very long, which makes it reach my desktop placed under my desk off to the side. The only reason I'm giving it four stars is that it's very costly at '8K. If it was less than 5K, I'd have given it five stars. Still, don't hesitate to buy it if you can afford it. It's a worthwhile investment, much more important to your health than buying the latest smartphone or other gadget.

Not so comfortable as I expected it to be. Mouse is getting heated after little overuse near the thumb part of the mouse and very uncomfortable and cannot work with it. If its connected to a USB hub port it kinds of trips in and out continuously. Relieves your pain from using the conventional mouse. I expected this to be more ergonomic than the ergonomic mouse I had previously.

Purchased this two years ago. Worth the money. Before using this, I had carpal tunnel syndrome and everyday my wrist and arm would pain. After using this, the pain is almost negligible. My hand too is healing. Note that its not your conventional mouse. This is a vertical mouse. Hold your hand in 90 degrees to the mouse pad - as though you are shaking somebody's hand. That's how using this mouse feels. But its worth every penny. 4 starts and not 5 because I expected it to last longer - especially after paying so much for it. After two years, it sometimes is not recognized by my computer and I have to restart my system. But in those two years, it worked perfectly well.

Compré este ratón por un problema en la mano y la verdad es que me ha resultado de mucha utilidad. Tiene un manejo sencillo y te haces a él enseguida. Es cómodo y ágil y la posición de la mano es buena. Ha mejorado la posición del brazo y ha disminuido el dolor considerablemente. Estoy muy contenta con el producto.

C'est ma seconde souris de ce modèle, la première commençait à manquer de précision après 4 années de service à temps plein (2011 à 2015). Soit une durée plus longue que les autres marque que j'ai eu avant. On prend vite l'habitude de ce type de souris et le double clic sert souvent. De plus, avec Win 7, Win 8 et Win 10, le clic droit est fréquent et les doigts sont bien positionnés. La lumière "bleue" peut plaire ou non, par contre, les témoins vert de réglage de précision sont intéressant pour certains logiciels (dessins notamment).

Not only is its higher angle than other vertical mice helpful in removing wrist strain, its well thought out comfort and usability make it a very productive device at that. In a few hours of usage, its fit feels natural. For those that gripe about the challenges of straining new muscles to position their pointer, they need to utilize more their fingertips and thumb, with its well sculpted cavity, for fine motion. We do that with pencils and pens (remember those inventions?) Anchoring your palm's side might save a lot of effort with small precise movements, with your wrist on a wrist rest too. And moving your arm for more coarse positioning in the "handshake" posture feels natural if not more so than flat mice. Optical, infrared sensing and 2600 DPI resolution should be high enough to satisfy many gamers, maybe not the hardcore twitch variety. But for desktop app use, sometimes dropping to 1800 and 1300 DPI (depending on screen size) with the pointer's acceleration sensitivity to the minimum (maximum threshold before accelerating) will help you improve slow speed accuracy. Browsing hyperlinks on a 2k screen is fine for me at 2600 DPI, but sometimes I need something lower for letter-precise aiming in editing text. The main buttons, including an ingenious middle button that's not forced to reside as the wheel, are considered to be a very light touch by a reviewer, but I measure left and right actuations at approximately 40 grams of force. I suppose knowing membrane switches can start down as soft as 25 gf should have taught me to take subjective anecdotes with a grain of salt. It feels as firm as many mouse buttons do. The clicky sounds are definitely pronounced. The wheel in between the left and middle button can be spun more quickly by operating it with the index and middle fingers. Tilt-to-move works like a charm and it's possible to move the mouse's body and not upset the screen blanker, thanks to an angled foot. Just follow the instructions on the insert. Although, it's not as reliable as a serious gaming mouse, which shouldn't even register 1/16000th inch of movement, for example. The highly mounted top thumb button (9 cm off the surface!) is easily struck if you're switching your hand from an unsplit keyboard on the left by touch for the first few days. So make sure it's not set to something that performs an irreversible action. It's the 'back' button by default and I have to watch out for it typing this review in a web browser. That's not an issue if you place your mouse in between split keyboard halves or in front of it. Before this review sounds like a shill, I am peeved this costs as much it does, and there are seldom sales nor used units available. And with reviews of low durability too, leaving me wondering if there are better values out there competing for Evoluent's mindshare and rank. And it costs more than many wired gaming mice which represent the pinnacle of performance, convenience and endurance, not that those should be the definitive benchmark for this market. But I'd have to conclude with so much product design executed well, we are getting what we pay for. And at least we get a gaming grade sensor that proves to be a very accurate tracker, even without a good gaming mouse pad. Hint: If you have to temporarily go left-handed, the thumb buttons can be programmed as left/right buttons and the mouse still operates comfortably, vertically and functionally.

This replaced my previous mouse from the same company after it died. This version upgrades several things. Grip is even more comfortable, which I didn't expect. So it continues to keep away wrist pain for me. An extra button is fantastic. And the sensitivity level switch is more user friendly than before. I have only good things to say about the ergonomics and quality as an office mouse. If you want this for gaming, be aware that there's an adjustment period to a vertical mouse. But the number of buttons and customization software are excellent. I only have one gaming complaint. The mouse will spin out on very fast motions. So if you game with low sensitivity and make large fast motions from the shoulder, this may not be the mouse for you. For everyone else, it should be a great option. Oh, and for hand size, my fingertips extend past the buttons on the XL size. I have normal-ish tall person hands. This isn't a problem, since pressing against the front edge of the button works fine. But you might want to consider one size larger than you would expect.

Cela fait des années que je me sers de cette souris et je n'en voudrais plus aucune autre. Elle est particulièrement ergonomique, facile à utiliser. Dommage qu'elle ne soit plus vendue par Amazon et qu'on ne puisse, en tout cas dans mon pays, la recevoir en point relais.
