Review Content Great product Drowns out other noises Good purchase A great product to use to block noise so you can sleep more easily in a hotel, on a cruise ship, or while visiting. It worked as it stated. It packed well, was easy to control. Highly recommend if you are sensitive to noise. White Noise Means Sound Sleep I have used a white noise machine myself for many years. I have both a standard bedside model and a travel model. This travel model is a gift for my son, per his request. White Noise Great Purchase! Outstanding outstanding Travel Noise Machine Does the Trick! I have a difficult time sleeping while traveling and this little device really helped a lot. It drowns out noises that would otherwise wake me. It was a lifesaver for a light-sleeper. Perfect Noise Works perfect, great white noise control.
