Logitech Ergo M575S Wireless Trackball vs Logitech MX Ergo S Wireless Trackball
Get the Logitech Ergo M575S. Unless you want a trackball that tilts, recharges and switches between two computers — then the MX Ergo S.
Logitech Ergo M575S Wireless Trackball
The cheap way to try a trackball: steer with your thumb so your arm stays still, comfortable for most hands, with much quieter clicks than the old M575.
Logitech MX Ergo S Wireless Trackball
The best trackball: you steer with your thumb, so your arm stays still. It tilts to 20°, clicks silently and lasts about four months per charge. US shops sell it as the MX Ergo S Plus, with an extra wedge.
