Query: Worked for Approximately a Week

The mouse hooked up nicely to my Vista PC/TV setup. After about a week of use the roller ball could not function up and down, only side to side. Approximately a week later, I smelled something burning. After I decided that it wasn't my lamp, I then realized that it was the pointer mouse on the table next to the lamp. The mouse was very hot, and seemed about to catch fire. I will be returning the mouse and looking for a better product. I live overseas and purchase many things online and this is my first review that I've ever written. I don't want anyone else to go through the same frustrations that I went through. There is a reason for the price decrease...it's called faulty materials.
