I dont see any Razer Replica anywhere. China branded gaming mouse is easy to spot as their boxing are usually in mandarin. But if you bought razer from Taobao or other china website. The boxing usually is mandarin already. Just make sure you clearly see the RAZER word as i dont saw any replica-ing the RAZER brandname YET

Mousepad if for FPS i would go for Razer Goliathus Speed also. You might wanna consider QCK+ from steelseries also. both is fine. You wont go wrong
