I LOVE THIS DEVICE and the 10 varieties of sounds it produces. Several years ago I purchased one for use in my physical therapy office. Everyone loved the sounds and we now have 3 units around the office. In addition, customer support has been fabulous.

BEST SOUND MACHINE IN THE WORLD. The most advanced machine of its kind. Great sounds, which can be set to alter automatically in response to changes in the external noise environment around you. This helps to mask disruptive sounds as they occur, to keep them from disturbing you. There is no other machine like it!


We LOVE !!!!!!!!!! this machine prior to having one we stayed at a friends house and he had one so we tried it out well that was it, we have had it for about 2 years and it works just like the first day and we use it every night can not sleep without it, the different sounds are nice and we change them depending on our mood I would recommend this to anyone it is a GREAT product.

Easily the best sound machine we have brought home! At first I was offended that my wife spent so much on this small box. But when it fooled me and I thought it really was raining outside….well there you go. Not some noisy “white noise” machine. Quality, real sounding effects. Because this machine is a box and not a flat disc like other sleep machines, they were able to put in a better speaker and sound system.
