Seriously one of the best pieces of technology I have ever owned. It looks like it would feel awkward in your hand but it’s actually extremely comfortable, took me about 5 minutes to get used to and I haven’t used another mouse since. I’ve had it for a couple years too, and it’s never failed or died on me, which is surprising considering it was only about $15 from Target. Everyone who knows me knows that I have a serious Hello Kitty addiction so this is probably one of my favorite things in life.
