Review on Logitech Wireless Trackball M570 Renewed by Wiktor Skowroski ᠌

If we do not take into account the trackball itself and the fact that it is wireless (for a trackball, in my opinion, an insignificant advantage), we get an ordinary mouse for 175, of which the mentioned logitech rivets a great many. strange, in my copy there is no protective glass of the sensor, they probably forgot to stick it . Has some pros: All the usual attributes of a mouse are present. 1.5 years of operation from one battery. Got cons: Manufacturing quality. - cheap plastic. - cheap clicky buttons. - loud crunchy wheel. - due to the inclined arrangement of the ball bearings of the ball (a tautology, but a fact) during fast navigation, it periodically jumps. - and of course you need to clean the ball from dirt more often. Trackman Marble was better, but scrolling was not implemented.
