3M™ Renaissance Mouse

With a traditional mouse, it can create a lot of pressure on the median nerve. The 3M™ Renaissance Mouse features a unique "handshake" design, keeping your arm in a neutral position for comfortable mousing. The handshake positioning transfers most muscle use from the hand and wrist to the larger muscles of the upper arm, reducing muscle load without sacrificing speed or accuracy. Designed for right-handed users. Top button operated by thumb for left and right clicks. Fully programmable third button. USB. Large: 3-1/2" to 4"
