Review on Renewed Logitech MX ERGO Advanced Wireless Trackball for Windows PC and Mac by Agata Olszewska ᠌

The device, in general, is excellent. High quality and comfortable. But the ball does not spin easily in all planes. Pros below: 1. Quality of materials. 2. Shape and comfort for the palm. 3. Changing the rotation of the entire manipulator. 4. Duration of work from one charge. 5. The presence of additional buttons. Different cons: Found only one, but a significant drawback. The ball holders are designed so that the ball rotates along one axis very easily and without difficulty. And on other axes, the finger meets resistance and the ball moves in jerks (as if an ordinary mouse had dirty legs or a flat surface). Because of this, it is extremely difficult to work with small objects, that is, accurate aiming is very complicated due to this problem with the ball and its holders.
