There are a few different configurations and some are better then others..
I have 5 of these and are nearing two years . many others have them as well.

Even some of the newer mars aqua lights are better then the original ones..
The thing to remember its the internet People usually flock to forums to complain about issues they have with a product more then brag about what they bought. Especially on here where there are so many who believe that if you do not buy the TOP Price product your buying junk.
With that said yes there are some of the so called black boxes that can even be dangerous.. i would say get them from amazon or somewhere you trust.
