Anyone out there using Livid controllers at all?

I have always been kind of intrigued by livid's controllers. The elements idea seems super cool, the Ohm stuff is good looking, i like that you can expand easily just by plugging in.

However, their products seem a little bit pricey for midi stuff and I don't see anyone really raving about their stuff anywhere.

Im wondering if anyone uses their stuff or has used it in the past, etc. If you have tell me your opinions.
