Over All it's a very good light. Came with out one extension bracket, and no user's manual. Customer service was great, including
a Email with a attachment of the user's manual, and was able to order a replacement extension bracket to replace the missing one.
I set it up in the DIY S3 mode. Lighting is very bright, and reset it a few times to get the right lighting for my tank. Only problem
that I found is that the clock runs about 5 minutes per 24 hours. So I find myself resetting the current time every few days.
Make sure to buy a CR1220 battery for the controller so you don't lose you setting if you lost power. Overall built quality is
very good, and I would buy it again.
