Bluetooth Ergonomic Mouse, Wireless Bluetooth Vertical Mouse 2.4G Optical Vertical Mice, Wireless Ergo Mouse Switch Between 2 Devices with Bluetooth & USB for Windows Mac Android - Black

Had to return it because of the long tail on the mouse. It is uncomfortable for the hand to have to rest on the tail, or rear lip, of the mouse. This tail also gets in the way of moving the mouse as I have a habit of lifting a mouse up occasionally during use to reposition it and the tail forces me to have to lift it higher than I'm used to. The grip, button action and hand positioning of the mouse were excellent, though. I'm also not too fond of the rubberized coating as it will probably start to peel off after some use.

I chose this one because it looked a bit more sleek than other similar vertical mice. I also chose it for the price! I have used one or two other jelly comb products before and I am never disappointed. Took a little bit to get used to the new layout but now that I have been using it for a while, it is second nature. It does go to sleep to save battery, so I just click the right click whenever I get back to it. Definitely recommendA

Very comfortable and intuitive. Only annoying thing is it takes times getting used to Bluetooth pairing and it goes into sleep mode too fast so I have to turn it off and on again throughout the day. That said, I like it and bought a second one for my office
