Semi-Vertical Mouse Wireless (Right-Handed) Medium w/Dongle

I've used other vertical mice for 10-15 years, but they were _too_ vertical. The semi-vertical angle on this mouse is much more comfortable for me. The flange is very helpful too, since it makes it more natural to move the mouse with my _arm_ instead of my _wrist_. I accidentally knocked it off my desk after having it for 3 months, and it stopped working. That was my fault, but I also think such an expensive mouse should stand up to a few normal accidents. I emailed their support, and they gave me a Repair Number. I'm mailing the broken mouse to them, and they're going to repair and return it. I'm very happy with the mouse itself, and the support.

I've had two of these now. One was given to me at work and when that one died within four months, it was just quicker to buy another on my own. I figured the first one could have just had a glitch. Apparently, this is just how they're made. The second one only lasted for four months. I really liked the support it gave my hand and wrist but will look for something that lasts.

This is the best mouse I’ve ever used. No more pain every day in my fingers, the top of my hand, or base of my hand. It’s a much more natural feeling and has helped me tremendously!!! I recommend to everyone!! Especially if you use a mouse all day at work! Get this, it’s 100% worth the money.

This works great product if you are having issues with your hand. I use it for work and at home.

Love this mouse. It helped relieve a pain I was feeling in the bottom of my wrist and helps train me to use my whole arm instead of my wrist for mousing. Responsiveness and accuracy doesn't compare to the MX Revolution mouse I was using directly before this, but the lack of pain is worth it.

This product doesn't work consistently more than a foot or so away from the dongle. I've yet to find a spot where it works all the time. Also, accuracy of actually achieving your click is not optimal. Get the wired version. It works like a charm and is great if you have arthritis in your thumb/forefinger joint like I do. Just to be clear, this would be a 5 star rating if it worked as well as the wired version.....

Got this because of sitting at a desk zooming my mouse around for work was killing my wrists. Ero professional at work recommended this (and some excersizes) and I've really noticed a difference. Takes a little to get used to but worth it! Definitely recommend! Please hit like to let amazon know the review was helpful. Thanks for the feedback!

The shape of this mouse will fix all your ergonomic woes, but I had to stop using it after about a month b/c it will not maintain power. It goes in and out and is massively frustrating. Also, the mouse takes batteries (woah, very old school) and connects via USB dongle. These are both workable, but would be better if battery were rechargeable and no dongle needed. I stopped using b/c of the connectivity issues and just can't go back.
