Anyone uses Cougar 700K gaming keyboard?

I have a few quick questions:

1) What color can you change the keys to?

2) does the software buggy? I was using Tesoro Colada, from this review, it's as bad as hell. Windows keep having a fun time not seeing the keyboard in a 9 mth. usage

3) it gives a 1 yr. warranty, has anyone has their "digital controller" drop dead after 1 yr.?
