They look OK, I can't say as I've ever seen an artsy mouse before. Logitech MX518 was pretty cool looking. But I can't forgive the choice to not include side buttons for forward/back browsing. Can't live without them now.
Wish someone would make a large mouse again. I have very large hands and most mice are small very and uncomfortable after an hour or so gaming.
First thing I look for is size.
