Pros: The mouse is inexpensive, fairly comfortable, and works on unconventional surfaces quite well.

Cons: Two main complaints about the mouse: - The mouse will often register more than one click on a simple click. This can be very frustrating in quite a few cases, where a second click changes everything entirely (from selection boxes to basic games). - Not necessarily a "con," but the way the mouse conserves power is a bit strange. The mouse runs on batteries, but has no on/off switch. Instead, it will automatically shut itself off within 5-10 minutes of idle time. It does conserve power, but it doesn't allow the user to control it at all.
