Tao Tronics used to make real junk (I had one), but they seem to have improved over the last year or so. But why buy an off brand when you can get led fixtures from reputable companies that are here in the US.
OceanRevive & EverGrow
Reef Breeders
Reef Radiance
They all have fixtures like the TaoTronics and offer much better support. And give they are all made in China, local support is a big deal. OceanRevive sent me a new driver (no charge) for a defective EverGrow unit I bought direct from EverGrow. That kind of customer service matters. I have a Chinese dosing pump that needs repair, but it costs almost $50 to send it back to China!
