June 5, 2009: This is by far one of the greatest products to come home! Just like the commercial ones you see in the airports only instead of a hole in the wall it looks like an actual flush handle. The great thing about this product is that you still can flush by pressing down the handle for those needed courtesy flushes. The sensor is adjustable so that you can move the sensor to look more at the user or look away. That way, you don't walk by it and it flushes. Everything that you need is included, minus "C" batteries, all you need is a standard toilet. They claim to flush 23,000 times on the 4 "C" batteries you need before changing, We'll have to see.
Oh, and don't worry about water getting in, its all sealed with rubber seals.

Same batteries and still flushing!

The motor struggles to raise the flapper, I have decided to remove it after replacing the batteries. Could have been that my water is heavy in metals and that it may have corroded something. I had left the included wrench in the tank so that I wouldn't use it, and it had rusted away thanks to my well water.
