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

Very Easy on the hand

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..

Lived exactly 3 years before the left click started getting stuck. The clicks are a bit loud but otherwise it was a decent mouse. I just wish it lived longer. But overall it's decent for the price.

Es de muy buena calidad y duración excelente

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.

I bought this for issues with my thumb over traditional mice. First impression it felt good and looked good. Problem is it never worked.I chose this because I wanted to get a brand name that I am familiar with; I did not want to have quality issues as I use my mouse all day long, it is very important, and I needed to relax my thumb from stress. Well, this one disappointed really bad.Once the dongle is inserted, the computers recognize it but the mouse itself never connects to it. I have tested with my KVM switch as I connect it to four computers I have, direct into computers, I tested side by side with my logitech, even interchanging batteries between them to make sure. No, it will not work. By the way, I have several wireless traditional logitech mice around the house, everybody in my household uses them, not a single problem, true plug-and-play years over years.Altough I was not able to test it, another problem would be that (according to the instructions manual) this mouse goes into a deep sleep after 10 min, and you need to click on a button to wake it up. Simply moving the mouse would not do it. This sounds like a battery saver which is totally unnecessary. I have been using mice for so long, I have never had battery problems with them just because they wake up by just moving them without any deep sleep. I never remember when the last time I changed a mouse battery was, they last so long. I think Kensington invented an unnecessary function which is at the same time annoying. I don't like the idea of pressing a button to wake up a sleeping mouse every time I return to my desk after a short break. I simply would not like to get used to something like that!

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.
