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.
Im also thinking maybe I just get another QCK+ (or clean mine, not sure how to properly) as I think its where its been worn down, and has some dirt on it thats not really helping?

Please help.

I didn't find the right solution from the Internet.
