I use two similar ebay fixtures, and my coral growth and color are both great. I have no real complaints, and yes I would have gotten a lot more features or even a slightly better quality Diode (Binning) for a LOT more money.... But my livestock doesn't care about thunderstorms or brand names, the spectrum is right and the output is well within the needs of my coral. This topic always bring out a lot of heated opinions, but in the end I believe you DO get what you pay for, but we don't all need a Mercedes-Benz to get to work, my Mazda does just fine
