Review on Logitech Wireless Trackball M570 Renewed by Stanislaw Banasiuk ᠌

Considering the high price for the Logitech M570 manipulator itself, I advise you, readers, the following: 1. Please keep the trackball box and receipt, as you are highly likely to incur a trackball due to a malfunction of the keys to the store under warranty for its replacement. 2. The USB radio receiver from this trackball should never be hot-switched; connect it only to a switched off computer. Otherwise, after a little less than a hundred switchings, the receiver will fail. As for operation: periodically, once or twice every two weeks, you will have to clean three radially arranged contact balls. The procedure is very simple - push the trackball ball with your finger through a special hole in the bottom and scrape off the dirt from the contact balls. The procedure, of course, is not aesthetic, but the point here is not in dirty hands, but in human nature - dead cells of the skin are constantly falling off. I use a Duracell battery for the trackball, it lasted me about six months of use in each of the trackballs, i. E. its power consumption is low. As for the quality of the plastic, the sound of the keys, the operation of the wheel, they completely suit me. If there were high-quality mics in the trackball, I would give it a rating of "five", and so only "three".
