Hi Jeff - I have two of them over the tank you sold me. The fixture seems to be very solid and the customer service is great. Had a complaint about one of them because I felt it was slightly dimmer than the other, RapidLED sent me a replacement unit and postage to return the other one in, no questions asked. Pretty darn good customer service there and they always respond to my emails within a few hours during business hours. However, I don't have anything to compare it to.
