Review on 🖱️ Enhanced Ergonomic Trackball Mouse: SANWA 2.4G Wireless Optical Vertical Rollerball Mice with Silent Buttons, 34mm Trackball, Adjustable DPI, Compatible with MacBook, Laptop, PC, Windows, macOS by Joy Vogelzang

Sometimes this trackball causes the cursor to not respond immediately or accurately. So I settled on two wireless trackballs, this one I prefer, and Logitech, which I turn off when it starts to fail, and switch to Logitech, whose ergonomics I don't really like, and my Logitech also works in this case when I drag something , it often pretends I released the left button when I didn't, and sometimes it double-clicks when I swear I didn't. If this trackball fails, turning it off won't help, and putting in new batteries won't help either. I usually turn it off, put it aside, and when I turn it back on the next day, it often works fine for several days. This could be a Bluetooth bug in Windows 10 or the Bluetooth hardware in my ThinkPad as my Logitech Wireless, which works reliably (except for the left button), doesn't use Bluetooth.
