If you buy an ergonomic mouse to prevent repetitive strain injury, you should be aware of the optimal weight of the ergonomic mouse. Let me explain why:
To control a mouse movement you always need two muscle actions, because a muscle can only pull (think of the reins to control a horse).
If the object moved by your hand is too light, you need additional muscle action to control this movement. The hand can only move an object without this extra (unnecessary) muscle action if the object has a certain weight.

It is exactly for that reason that an ergonomic mouse should be weight balanced. During our two years of field research we have established the optimum weight of an ergonomic computer mouse to prevent unnecessary muscle action. As you can imagine, this has been applied to your ergonomic HandShoe Mouse. The weights are dependant on the HandShoe Mouse sizes Small, Medium and Large, which are made for different hand sizes.
 
As a result, you might experience the weight of the HandShoe Mouse is more than average. In general, however, standard and so called ergonomic computer mice are far too light to realise optimal muscle relaxation.

If you think the mouse is too heavy to your liking, you have an option to remove some weights from the weight chamber in the HandShoe Mouse, although we do not recommend  it; you just have to get used to it.

During our fundamental and field research we also noted that many people tend to lift their mouse to keep the cursor on the screen in the same place. This requires a gripping action which is actually not necessary. For that reason we do not want you to lift the mouse and there is no need for it either:

Just Roll On It's Side

If you want to move the HandShoe Mouse without moving the cursor on the screen, you just roll it on its side by lightly pushing down the side of the HandShoe Mouse where your little finger is resting.
You can then slide the mouse over your desk and the cursor will stay in the same position.
 
Finally, to enhance control of the mouse, we also advise you to set your cursor speed at around medium. This is easy to do if you follow the instructions of the short video below.
