My son had this for a few years. He has a bunk bed so it was really nice for him to be able to see the time on the ceiling. I think one reviewer had a defective unit as the alarm on his worked fine. It was a series of two beeps which would get closer together and then constant. It woke me up in another room if he didn't get up. After about 2 years, the lights on the projection broke and there wasn't enough left to tell what numbers were lit. Overall it was a nice clock, despite the short life.

I've had this clock for a few years, it's great, you can use it with just batteries or you can plug it in.

I love the idea of having the time on the wall at night. As for the daytime illumination, it is very difficult to see. This would be excellent if they put a little more time into perfecting the daytime display when you cannot see the seeling display.

I bought this for my 13 year old who has a loft bed and had trouble seeing her clock. It has worked out great. She loves it and is very happy. The projection on the ceiling is clear and easy to read. So far no problems at all.

After reading some of the reviews I was a little hesitant to purchase this clock but I'm glad I folled my instinct and bought it. It is easy to set up and shows a perfectly clear time on the ceiling. We had one before that was blurry and you couldn't get the time to stay in place on the ceiling. This is a great value for the $$$. I would recommend it to anyone.
