Aqualight Digital Day Night Timer

Been using for about a month now with no problems or hicups. Liked it enough to buy another one for my other tank. Well this new one's night and day outles are reversed for some reason. Other than that, it also works satisfactorily.

The unit has been driving me crazy, until I realized that the timer runs slow. It loses 12 hours a day, exactly 30 seconds a minute. The manufacturer is sending a replacement.

I've only been using it for a week but, so far, it's been doing what I expected. Lights on and lights off at the correct time. I'm assuming that the battery will let it hold its settings during a power outage. I'm happy with it at this point but it would have helped if there were three outlets for daytime.

When it works, it's great, but it loses the programming every time I turn the strip off or the power goes out.
