some important flaws. The lights brightness are adjustable but still too bright for sleep. Research shows that sleep quality is reduced when room now sufficiently dark, even when unnoticeable. It would be great to have the alarm gradually turn on and the worst is that the sound samples are only about 5 seconds long which makes them very obviously repetitive and very hypnotic rather than relaxing. With memory so cheap, it would cost like 1 cent per machine to make the sound 5 min long instead of 5 seconds long. Why give up so close to the intended objective? Best Sound Machine on the market! This was a gift for my daughter who has insomnia. After researching similar products this one had the most options, the best reviews and was well priced. I want one for myself. The best is my 21year old is now finally sleeping like a baby, and cant live without this machine. My only complaint would be to remove the description of this product as being a "white noise" machine, (when doing a quick search on this type of product) it deters consumers into thinking this has only one option....white noise...as in little girl on poltergeist in front of the tv, when you have an outstanding huge selection. Call it a sleep sound machine....and get your product into department stores. I had to order online, which was perfect, as no-one carried your product but I was hesitant only cause I waited until last minute. Sound Soother
