Review on Logitech ERGO M575 Wireless Trackball Mouse with Easy Thumb Control, Precision Tracking, Ergonomic Comfort Design for Windows/Mac, Bluetooth & USB Connectivity - Graphite by Scott Reeves

Not a bad product. Especially for the price. My only complaint is one that most people probably won't have. When working on detailed designs, I often try to get the mouse to sit on that exact pixel when I click. But since the ball is sooo light and rolls so easily (I know, yeah, who's complaining about the ball rolling smoothly?), when I click, the exact spot I had the cursor on can change a bit . I decided to trade the ball. for ball bearings 34 mm. I got one from Amazon for $9. By default, the ball bearing was too reflective and didn't provide enough contrast for the mouse's optical sensor to track its movement. So I wrapped the bearing in a paper towel with some vinegar (don't let it steep for too long) for a few hours to etch the surface a bit. Then I rinsed off the vinegar, dried it and applied a wax finish. Now it's a powerful ball that the mouse's optical sensor sees perfectly. It takes some effort to move, which is good for Right on the Pixel's design work. But it spins smoothly and quickly when I need to browse or browse normally. This review isn't for everyone, but if you're one of those people who have the same problem, I hope I've helped you. Because I was hoping to find someone who had the same idea when I planned it and bought everything for it.
