Rockstick is the only ergonomic mouse that offers hand-clicking rather than finger-clicking. In the handshake position, users of the Rockstick mouse will “click” simply by leaning the mouse to the right or left, taking pressure off of the fingers — a leading cause for mousing-related RSI.
The Rockstick mouse takes the latest approach to mousing — a 70 to 90 degree vertical one. Unlike a traditional mouse, where you lay your hands flat on the mouse, vertical mice like the Rockstick rotate your hands by up to ninety degrees, so that they are in handshake position while mousing. This minimizes pronation, and, for many people, is a much more natural solution. You will draw on the strength of the entire hand. The Rockstick is also fully ambidextrous - the grip can be easily swapped to fit both left and right-handed users (see the switch under the base), or to allow for rotating between hands and give the main hand a rest. Due to ideal button placement, there is no need to hover fingers for hours on end.
Choose the size mouse for you:
To get the right size of mouse for best fit, measure from the top of the middle finger to the crease where the wrist meets the hand. Choose Medium for up to 180mm; Large for over 180mm. If borderline try the smaller size.
