I actually own 2 of these. I purchased them 2 months apart, one for each childs room. After a few months they started turning themselves off, the kids would wake up immediately. Very frustrating to say the least. I can get them going again by flicking the volume button, or turning it off then up again very slowly. A terribly poor quality product, but we are very dependent on white noise in our house...I will be buying a better quality prouct next time.Get more detail about HoMedics SS-2000 Sound Spa Relaxation Sound Machine with 6 Nature Sounds, Silver.
