I used the Apple wireless mouse for years and always left that it was too small and my hand was a bit cramped using it. I saw a few designers using this specific mouse so I bought it on the reviews I read with the hope that it would be as good as everyone said it was. It is! And then some. Feels ultra-comfortable, it's very functional and solid to use all day. The only improvement I'd suggest is a version with the Apple multi-touch gestures ability. But, even without it it's well worth the price. If you only buy one mouse, this is it :)
