I have three of them in service now. One for the 10K, one for Actinic Blues and one for the sump.
Since you can use one remote for up to 4 times, also nice - except that the remotes are cheap.
I have my lights set up so that a couple of days a week, the clouds are out (less lighting). Helps a bit in ridding myself of the last few spots of HA (its a nice brown, just has not let go yet).
Having the lights on two different timers also let me set up a sunrise/sunset scheme.
The timer on the sump is nice as I use an auto feeder in the summer while I am at camp. Sumps turns off, 5 minutes later, the auto feeder kicks in. Twenty minutes later sump starts. Since my sump is downstairs, also makes turning it off via the remote nice when I want to work in the tank.
The timer it self is battery back up - so no loss of programming or time when the power goes out.
In short, I love them!!
