Query: Works well, but steer clear!

The mouse pad does not look as nice as it does on the photo - it is actually rather dull and cheap-looking. I cannot complain about performance as tracking is very good. However, and I can't believe no-one has mentioned this in earlier reviews, it smells absolutely horrid! The smell is hard to describe - like new plastic, but also like musty towels and sweaty gym-shoes! Totally gross....
