Review on Logitech M570 Wireless Trackball Mouse: Ergonomic Design for Right-Handed 🖱️ Users, Compatible with Mac and Windows, USB Unifying Receiver, Dark Gray (Discontinued) by Hideo Ebara ᠌

This trackball was bought to replace the old Logic T-BB18, which served me faithfully for probably twenty years (now I don’t remember when I bought it), until the buttons began to “be weird” at all. I did not see any differences in shape and ergonomics, there are small differences in size, but very insignificant within 5mm. The workmanship is very good, not worse than the old one. Only here is the ball, somehow not impressed. Light blue paint did not seem very good to me. I changed it to a ball from the old one, since they turned out to be identical in size. I did not understand why wireless is needed. The trackball is remarkable because it stands in one place, put it “and forgot” once, you don’t have to crawl around the table like a mouse, and therefore the presence of a wire does not worsen its operation in any way, because it does not depend on its presence in any way. This is a critical parameter for the mouse, because you have to move back and forth on the table all the time, especially if there are large documents and drawings. In addition, batteries or accumulators are needed. They would make the same wired trackball as my old one and it would be great. I think it would be cheaper by a thousand. On the other hand, there is not much choice. For the price of quality, there are no competitors, or a couple of Chinese unknowns, or from 7 tyrs, this is already too much.
