Review on Logitech Wireless Trackball M570 Renewed by Vassil Nikov ᠌

The high price does not mean the special quality of the parts. Inside are standard components as in ordinary mice. The trackball is ideal for a sofa, a bed. I don't know of alternatives yet. I do not regret the purchase. Pros: Range, stability (there was no loss of communication), duration of work Has some cons: After 3 months, the OMRON d2fc-f mikrik at the left button died. The button started working twice. I didn’t take it to the guarantee, because they would give the same thing for another 3 months, and I would have to wait. I installed a mikrik from an A4 tech mouse. The case screws are under the rubber bands and under the battery (you will have to make holes in the sticker). I recommend not to disconnect the optics during soldering, static can ruin the matrix.
