I'm going to make this short. I bought a 5.5G Aqua-tech starter kit. The type with the net, heater, filter, light-in-lid, etc. The lid with the build in light almost started a fire in my house. Not only was the light burnt out, but they put a double-ended light holder in a one light slot. On top of that, the cord was knotted behind a plastic protector that I unscrewed to look at (I could see it knotted through the protector).
The light was off but plugged in before I started my investigation. I lifted the lid and a huge spark went off. I just don't want this to happen to anyone else.
Everything else works fine. Be wary of the tank lid, though.
