I've tried so many white noise devices. I have a Hatch Rest, a SkipHop portable owl one, one built in to a teddy bear.this Yogasleep GO device is amazing. The sound options are great, the volume levels are great, the battery life is wonderful. And the best part is it doesn't turn off after a specific amount of time like the SkipHop owl (which only lasts an hour max). So it goes all night which is a vital feature.See full review
