TECKNET Ergonomic Mouse, Rechargeable Vertical Ergo Mouse Wireless, Silent 2.4GHz 6 Buttons Optical Carpal Tunnel Mouse

It looks nice and fits very well in your hand. It works perfectly and has an on/off switch to save battery. It also comes with a charging cable, but the battery lasts a long time. It connects through USB. At first it feels a bit different if you’re not used to this type of mouse, but once you adjust, it’s very comfortable and helps prevent pain if you work long hours on the computer.

Very nice to use, and for the price I can't complain much. Would prefer the surface not to be that smooth but I know adding a more grippable texture would increase the price. Overall a solid product especially because of the ergonomic value it adds

my old mouse was the usual flat style, but I wanted to always give a try to this ergonomic design and I must say this one is great once you get a habit of using it. The battery life is great, and its quite smooth with various levels of speed. The only issue if I can point is that the connecter is the old USB. Now Mac does not have those USB slots anymore so I had to use a connecter from old USB to USB-C. They should either give the connecter in the box, or change the connector to USB-c

Honestly, my hand feels more comfortable with this mouse, but my hands are small, so I gave it to my brother. He says that: It’s very quiet — you can’t hear the clicks at all. The battery lasts about a month with all-day office use. It’s very nice to use for work. The glides are good, but they could be better, even if that meant a slightly higher price. A good choice if you care about those things.

Good quality and works well. Drawbacks....a little large making it a bit uncomfortable for smaller hands and finish is very slick requiring a firm grip to move around. This results in hand cramps and is generally undesirable in a mouse.
