Your wrist's been aching since lunch. The M575S trackball fixes that without you relearning how to use a mouse. Thumb control keeps your hand planted on the sculpted body while the ball does the moving. Ergonomists certified it to cut forearm muscle strain by 25%. Five buttons, three of which you can remap in Logi Options+. Works over Bluetooth LE or the included USB receiver. One AA battery lasts up to 18 months
