I have owned three Coralife Power Strips units. Two were the digital and both cooked to the point that I could hear and smell them burning. They were mounted in a very clean place an were less then a few weeks old. After the two digitals burnt out, I exchanged them for a different model, That has a bulit in manual set timer. Seem to be worrking well for the last year.
I had a fire in my house. The fire investigator said the power strip which was the coralife power center started the fire. The aquarium eventually melted and put out the fire.
We were not home at the time. We live out in the country and our neighbor's are too far from us to notice if there was a fire until it was too late. Also, it took the volunteer fire department 30-40 minutes to get there.
We would have lost everything if the aquarium wouldn't have put the fire out.
I have one of the digital versions. Had it up for about a year now. Never had an issue with it. This thread has me nervous because it's in my office at work and I travel a fair amount. But, I have a very small draw on it. Its a nano so just a single 250Wmh balast, an alternative flourescent fuge light, and a Koralia nano.
