Query: Well worth thr price!

We first ran intyo the Enviraspa at a B&B in Seattle.We have since purchased our own.Without getting into a fruitless debate as to how the sounds actually compare with the forest or the beach. if you have occassional sleepless nights, we have found it very usefuland an effective aid to sleep. We recommend it highly!
