Review on 2.4G Wireless Ergonomic Computer Mouse with USB Receiver, Finger Rest, 5 Adjustable DPI Levels - Mobile 2400DPI USB Mice for Laptop, Chromebook, Notebook, MacBook, Computers (Wine) by Kyle Bonnell

Decent size (ie not too small but could be bigger). sleep function is ok; Move or click to wake it up. Cursor control is good; accurate with multiple speed levels to choose from. Scrolling is the problem. As others have described: Normal scrolling sees the screen move up and down without moving anywhere. I found faster progress by scrolling very slowly. Strongly annoying. Not at first, and now it's well outside the return window. It's not even worth the $8.49 I paid in March 2021 (Interestingly, VicTsing's product listing no longer exists, but same mouse, same manufacturer model number. In fact, I've bought three more mice from VicTsing and found that VicTsing brand mice are no longer available from Revain ).
