Review on Renewed Logitech MX ERGO Advanced Wireless Trackball for Windows PC and Mac by Aneta Smoliska ᠌

He gets tired of the mouse and sometimes his wrist starts to ache. Compare with Logitech Marble. From MX ERGO, as from a mouse, the wrist gets tired, plus, besides, the thumb began to get tired. This trackball is not symmetrical, so it will not be possible to change hands for unloading. Conclusion: The product is of high quality, but it did not work for me.
