## Questions & Answers

**Q: I have very shaky hands, would the roller ball mouse help me be more precise. I want it only for artwork.**
A: Hello. Compared to “normal” mouse is the trackball mouse good for a person who has shaky hands. If you choose our ProtoArc EM03 trackball mouse, you rest your hand on the mouse lightly and use your index finger to navigate. The mouse does not move, only your index finger moves. If you have any other questions, pls feel free to contact us any time.

**Q: When I turn the mouse over to access the buttons on the bottom, the ball barely holds in place and falls out after any little shake. Is this normal?**
A: Yes. The ball isn't held in at all. You need to be aware and remove the ball every time so as not to drop and damage it . The pins in tha ball cup need to be cleaned regularly so this is an excellent time to check out as well. Hope this helps.
