TECKNET Ergonomic Wireless 4800 DPI Gaming Mouse

To be honest I don't understand what other reviewers say because I haven't had any problems with this mouse at all. Not for work, not for gaming, not for programming. It works perfectly fine for everything and such a cheap price?!
Maybe you all should check your own problems (like your PC/laptop USB ports, or your own computer) before blaming the brand. I've bought multiple mice from them, and they have never failed me,ever.

Works brilliantly on my Yoga7i-14ITL5 running Windows 11 Home. I only wish I could change the accent color like on the corded model GM299, which I loved for many years. I hope this one lasts even longer! Thanks!

These are excellent mice well built and comfortable to use ifor any purpose..

...You don't use a mat with a glossy surface, or any kind of surface that's black. Yes, they actually tell you this doesn't work well on dark mats. Odd. The laser goes kind of jittery. The mouse itself feels good in the hand, good response on the buttons, and has excellent customizable software. It takes 2 AA batteries (you can use rechargeable ones if you like). Caveat: the weight of the batteries renders the glide a little slow. You will need to use a bit more effort to push it around. Might be an issue, or not. I ended up just getting a mouse that works well on a dark mat with a small rechargeable battery built-in. I got fed up with the jittery pointer and weight in the end. Still, this is a quality product, and some will appreciate the fact you don't need to toss the mouse away when its built in battery goes defunct. The software is excellent (you download it from the website) and the button response/dpi settings are top notch.

Great product
