@mAson I can't fault the Rival tbh, the quality is on par with zowie products if not a little better imo.
Good set of drivers and configuration (if you do that sort of stuff)
Works great with SS quick heavy mousepad
size wise though it's bigger, more of a DA feel so takes some getting used to obviously depending how long you have used zowie.
I got a dirt cheap deal at pcworld (i know dirty shop) but they were stupidly selling a rival with headset and QCK hvy for £25.. but selling the components separately for 40+, it's worth a gander.
