I bought this mouse a couple years ago and loved it. It fits in my hand well, is pretty, and does what I need it to do without a billion extras to get in my way. The scrolling wheel eventually gave out due to heavy use (I use it way more than the average person). I replaced it with the same mouse because it was great. And that's where this all goes wrong.
I take the batteries out when transporting the mouse because they die in my purse otherwise. When I put the batteries back in I noticed a bad smell, which quickly turned into a burning smell, which quickly turned into the mouse smoking in my hand. Needless to say the mouse was burning.
So as long as you like it when your electronics catch fire in your hand you'll enjoy this product.
