Um... well, I had a pretty good experience with them... knock on wood. I bought a nice 4 foot MH system from them at the end of the summer, and it has worked beautifully so far. Again, knock on wood... I've heard lots of bad things too, but I'd also heard that Odyssea had updated their ballasts to electronic ones in separate chassis on the new models they're currently selling, so I decided to take a chance on them... and once more, I knock on wood!
