XCM KO GEAR for PS3 and fighsticks reviewed?

Was looking into buying the XCM K.O GEAR adapter for ps3 and my custom madcatz TE fighstick but i<m a bit on the fence about the input lag as there are no reviews anywhere.

I was wondering if anyone in the forum actually tried the adapter and can say if it is a worthy buy or just some more junk to throw in the garbage?

Thanks any information is welcomed!
