I've read several reviews on this product and I thought I'd throw in my two cents. I've read several reviews where people have had multiple problems with this product, but I have bought several of these and have not encountered the defects people mention. People should know, however, this power center is in NO WAY waterproof. If you spill any water, especially saltwater, into the device it will short out and you will likely destroy the timer.All of this said, if you have a simple tank, you're looking for a relatively simple light cycle, and aren't looking to run multiple powerheads or a wavemaker, this product works just fine.
