Logitech M570 Wireless Trackball Mouse

Customers find this trackball mouse to be the best desktop trackball ever, working well and being comfortable to hold with average-sized hands. They appreciate its ergonomic design, noting it keeps hands from moving around and reduces wrist strain, while also helping with carpel tunnel discomfort. Customers consider it an excellent choice for the money, though opinions about durability are mixed, with some reporting it lasts about a year while others note the primary button wears out quickly.
