Bests & Worsts Reviews from Amazon

I bought this because the majority of reviews were positive. There was one angry review mentioning how it's on a 10 second loop, but because of how it was written (no offense to the person who wrote it) and because of the other reviewers who say they can't hear a loop, I went ahead and believed that review was wring. They were not wrong. The sounds are on a 10-11 sec loop, and your brain picks it up and then drives you crazy. I'm returning it after one night of usage. My advice is to look elsewhere.
