I love mine! I have the Reefkeeper Lite. I love having the digital pH and temp, and I can shut down pumps and powerheads at the touch of a button for feeding time, water changes, etc... I also don't have to reset the timer for my lights every time the power goes out like I had to do with my manual timer. Very much worth the money I would say. The only bad thing I experienced was that I had a bad head unit when I got mine and had to send it back for a replacement after feeling like a fool not being able to get it working. :P
