Lenovo Thinkpad MOBTC9LA

Numerous problems – I received one of these from work and have been using it for the past six months. I have had no end of problems with it and ended up buying my own budget mouse to take its place. - Randomly disconnects while in use every couple of days. It may reconnect itself after half a minute, or it may not. Removal and replacement of batteries may force it to reconnect but this may take several tries. - Random keypresses when it reconnects. This has destroyed work on several occasions through reloading or submission of web forms. - Left click flickers on and off when pressed, causing double/triple/quadruple clicks. Drag and drop is simply impossible. - Mouse wheel stops working randomly. Starts working again hours or days later just as randomly. - Tracking is good... on good surfaces. Fails frequently on uneven surfaces.

Summary: I expect better reliability from a $5 mouse. Horribly substandard for a brand like Lenovo.
