Kensington Ergonomic Vertical Wireless Mouse (K75575WW), Grey/Black

Have been using the Anker vertical mouse for years because I really like the feel of it but have a lot of issues with the quality of the mouse in general and specifically the mouse tracking. I've been looking for something with similar ergonomics but better build quality. So far this mouse seems to meet my requirements. The lip at the bottom of the mouse took a little while to get used to but I don't even notice it anymore. The charge lasts for a long time. The scroll wheel feels nice and the mouse tracks way better then the Anker one..

Purchased to replace another brand of trackball input devise. Wanted to avoid the stresses that have led to carpel tunnel in the past. This works very well.Takes a day or two to get used to it's height (moving hand around on desk I he'd to learn to avoid hitting this). But I had tried another brand that was only slightly taller and could not stop knocking that one - how frustrating. This Kensington has not been a problem at all. Tracks well, Very responsive. Comfortable to rest the hand on; buttons function well. Great wireless function with included plug-in USB receiver. (Have not tried the Bluetooth connection possibility.)Wakes up (after 10 minute inactivity) quickly. A bit delayed awakening the first time after an overnight extended computer sleep. But I can live with the 3-4 second wait once a day if it means no recurrence of carpel tunnel symptoms. [UPDATE: Once I changed the battery (even though it was functioning fine), the wakeup time was MUCH quicker. In future, a growing delay in the wakeup time will just be an indication that a battery change will be happening soon thereafter! Glad to have learned that.]Very happy with design, execution and the price.

I only recently learned of the "vertical mouse" concept, and I was intrigued to try it out. This is the lowest cost vertical mouse I could find so I figured it would be a good place to start without having to drop $$$$ on some of the more premium options.There's definitely a learning curve and it can be frustrating because you will be less precise at first. However after about 3 work days of using it, I'm starting to get used to it and I can definitely say it is more comfortable than a regular mouse. It has lots of dpi options, moves very smoothly, and only needs a single battery (most of the standard mice I have usually require 2).The only cons I have are minor. I believe this might be just slightly too small for my hands. If I try holding the mouse like in the product pictures, the pinkie rest is too far back and my pinkie ends up dragging on the desk. If I angle my hand to use the pinkie rest, my thumb ends up floating away from the thumb groove. However I've never measured/sized any of the other mice I've used, and I've seemed to naturally settle on a grip I'm comfortable with so no biggie.My only other criticism is this mouse is comically lightweight. Some people may see this as a plus, but I've inadvertently knocked it off my desk a couple times, and it doesn't take a lot of force for it to go flying.So if you're looking at trying a vertical mouse, this is a good first option for the price.

This mouse felt great in my hand and my hand/arm felt comfortable resting and moving with it. I had issues with lag starting on day one and I shipped it back on day two to request a replacement.The support team was responsive and fair. They mentioned that the mouse worked normally (once they had received the one I had sent back) and that I might have an interference issue; they refunded my money.If this mouse works the way it sounds like it does, then I would really like it and recommend it. I don't know from experience, though, and that's a bummer because it felt better in my hand than any other mouse that I've used.Great ergonomics and tip-top customer support.

I really wanted to like this Kensington vertical mouse, but I don't, and the primary reason is size (it's too small). I wear a size XL work glove and measure 8" from tip of middle finger to palm/wrist transition.I should start by telling you I am a long time vertical mouse user (past 3 years) at home and at work and it definately relieved my carpel tunnel symptoms within a month of switching from a traditional mouse. I have the wireless Sharkk model (which looks identical to the popular wireless Ankar model (like a shark fin)). The Sharkk/Ankar model has been great, and fits my hand well from a depth perspective (tucks deep into my palm and finger tips do not extend past the buttons or end of the mouse) but like anything it isn't perfect as my pinkie drags on the mousepad since it isn't supported by the mouse and/or the mouse isn't tall enough.I was considering the Logitech MX Vertical wireless mouse as a potential upgrade but I had the chance to hold a display model at Staples and it is small and too light/flimsy feeling (particular given the near $100 price tag; shame on you Logitech). Then I noticed the Kensington Ergonomic Vertical Mouse (which seems identical to the Autley Ergonomic Wireless Vertical Mouse, but has the advantage of replaceable batteries over rechargable). The most intriguing thing was the "appearance" of a taller profile and the shelf on the right side for your pinkie. Well it arrived today and the pinkie shelf works (mostly, now only the tip of the pinkie drags instead of the whole figer), but it is absolutely not taller than the Sharkk/Ankar, and unfortunately it is not as deep as the Sharkk/Ankar vertical mouse either.If I tuck the Kensington into my palm (like a baseball in a glove) all of my finger tips extend beyond the end of the mouse by more than half a digit. And if I hold it in such a way that my figer tips are on the buttons, then there's a big gap in the back between the tail end of the mouse and my palm, which lacks support and creates an awkward grip.Also the Kensington vertical mouse failed on the most critical component for a vertical mouse - it is less vertical than the Sharkk/Ankar. It actually rotates your fingers and wrist back towards the horizontal position (not as much as a standard mouse obviously, but more so than the Sharkk/Ankar). I will try to add pictures to show what I am talking about.In any event this Kensington mouse is going back. I am considering trying the Delux Ergonomic Wireless Mouse with Removeable Wrist Rest (M618Plus), but I fear that one will be too small as well. I suspect most of the stock pictures for computer mice are taken with small children holding them.
