The customer service is great with Martin too...
I had huge problems with my (home built) RGBB going out of line all the time. After about a year of trying different fixes, i opened up the kvant red and found the problem. Despite it being out of warranty and my having opened it up, Martin got it replaced with a new design and I was only charged labour... This was all done in time for my next show, so big thanks to Martin and the guys at Kvant...

After (excuse the wonky iPhone pic)
Cheers
