I own the Logitech G303 which is severely under-rated considering it has a great sensor and its RGB. It's more simple than all the complexity's of the G502.
I have the Tournament Edition Chroma and its been working fine other than a few typing issues which I have resolved I think. RAZER TOURNAMENT EDITION KEYBOARDS COME WITH CARRYING CASES FOR THE CHROMA AND POUCHES FOR THE NORMAL.

I own a Razer Blackwidow Tournament Edition Chroma. Its been not working sometimes when I am web browsing but never when I am gaming. After a little bit it seems to start working again. All the lights remain on but when I type it doesn't work.
