The BakkerElkhuizen PRF Wireless Mouse is an ergonomic vertical mouse that helps to prevent strain on the wrist and arms. Using a traditional mouse can cause pain and discomfort in the shoulders, lower arms and hands. A vertical mouse mostly prevents these problems. The angle of the mouse ensures the correct arm and wrist position. The shape of the mouse ensures the palm of the hand makes contact with the mouse correctly and it is also held in a handshake position. The PRF Mouse has 4 conveniently placed buttons, a scroll wheel and a wide DPI range. It is suitable for both USB-A and USB-C ports thanks to the included adapter.
