Just don't waste your money.The actual product is plain crap.The product does very little of what is described on the manuel.1. The light is so dim that you can barely see the projection on a wall in a dark room, and the intensity cannot be adjustted.2. The alarm is extremely quite and it stops automatically after 80 seconds. (Are the designers idiots????)3. There is no automatic adjustment of time using radio (or whatever they call it.) You have to adjust the time all by yourself.4. The adjustment of time is very confusing since there aren't enough bottons.5. The outside weather detection: haven't used it, so no opinion on that.To sum up: DO NOT BUY IT.*(If the rating has negative stars, this product wouldn't get one star as my rating.)
