Item never arrived, and so for that reason, and that reason alone, I have to give 1-Star. (The item was sent from Japan to the UK, by an untrackable service!) However, Seller did give me a full refund, and a very sincere apology! I appreciated this very much, so, I want to say 5-Stars for their customer service! It's just a shame this hard-to-get mouse never arrived, and can't be replaced either!
