Personally, I've always had a soft spot for Nyko's AirFlo series of gaming peripherals. It's claim to fame is "AirFlo" shell that lets air from a built in fan smack your palms with cold, breezy goodness. Gimmicky, yes. But what's not to like about mice and controllers with a built in fan to help keep your hands sweat free during a long gaming session?
I'll be honest that, as a controller, it's mediocre at best. It's a little larger than most, but still comfortable to hold. The buttons and triggers are good, but the D-pad and sticks could be better. Maybe it's the open air design, but it does feel a little cheaper than it should.
