cold fusion nitrous

Im looking at buying a system from this outlet, Im just wondering if anyone has used their gear and what is like for quality
www.coldfusionnitrous.com

they have good prices on accessories. No experience with their complete systems but their bottle valves are cheap made in China crap and leak like a syv

I have their fogger system. I have never had any problems with any of their stuff. imo the quality is very good.
The only problem i've had with leaking bottle valves was with an nos bottle.
