Has anyone ever ordered anything from aquacave.com?

I have as well. I ordered a retrofit light fixture and some 6ft geisman bulbs. They sent the wrong size light fixture and the bulbs were broken. I called them, had to leave a message...had to call back. Finally spoke with someone, they sent a new order out right away. I had to deal with, but not pay for, the shipping back of the wrong light fixture which was a pain.
All that being said...things happen and they made everything right. They do have some good stuff that is hard to find other places. I would order from them again.
