Review on 💪 Enhance Your Gaming Experience with ELECOM Left-Handed Wireless Thumb-Operated Trackball Mouse - 6-Button Function and Precise Optical Sensor by Roger Mitchell

I bought 2. Both were in stock. They work fine. The authorization can be set. Since I have a slight twitch I find it best to use it low. The buttons are strong. The ball appears to be a standard size, so if you lose it there's a replacement. I also have Logitech and Perixx trackballs. The quality is similar but it was cheaper. The function of the button is programmable. I'm happy.
