Wonderful device!
This is an awesome device that provides great white noise to help sleep. We bought for our infant's room to muffle the sounds of the house (door bell, dog barking, tv, etc...) and it works wonderfully for that. We bought 3 in total. 2 for our children and one for us. It's well built and has adjustable sound (volume, pitch). On full blast, it's pretty loud.
