Review on Logitech Wireless Trackball M570 Renewed by Wiktor Janic ᠌

Six months later, the left mouse button began to stick, took it apart (5 screws from the bottom - 1 open, 3 under the "legs" and 1 under the sticker in the battery compartment), dripped alcohol on the button, pressed it 10 times and that's it! Works like new Pros: Comfortable, sits well in the hand, the wrist does not get tired. To work as a programmer, that's it! Got cons: Alas, playing games that require the speed of mouse positioning will not work (and if it does, then the pleasure is not pleasant)
