Are coralife any good?
NO!!! I bought the dual timer setup 3 months ago and it has already wore out!! I would not suggest getting one. Both timers got stuck and would not spin around. Good idea for a power strip but they should update it to a digital timer on it. I ended up getting the 15amp digital timers at Home Depot and have had great success. They are battery back up systems that keep the time when the power goes off. You can also program many different settings in them. Price was a little bit high (20 dollars each) but they are reliable and will save you money on energy when you do not 'have' to run all those pumps and lights constantly.
