Review on Logitech Wireless Trackball M570 Renewed by Jnis Labucis ᠌

This is already my second trackball from Logitec. The first one was wired. I worked for 8 years. But I wanted something new. I bought this and at first I was not overjoyed - there is no connection to the computer, the cursor is fast, the ball is smart, the mouse is just an extension of the hand and fingers. No tunnel syndrome. But a year later, the buttons stopped listening - they don’t highlight the words the first time, you need to press the button 2-3 times to get the result. At first I thought that the driver had crashed, but as it turned out, the trouble was in the buttons themselves. The flimsy plastic has lost its shape and the platforms just don't reach the buttons inside the mouse. At first, sticking a small amount of paper on the platform helped. But a month has passed and - everything is new . I don’t know what to do - trackballs are very convenient for me, but is there any point in buying a new one? And there are no other thumb trackballs.
