I ordered this product from and received it three days ago. This seems to help so far with my husband and I having a more restful, uninterrupted sleep. We have three dogs that sleep in our bedroom, and my husband has allergies. I noticed the first two nights were much more restful. He forgot to turn the device on last night, and I noticed our sleep was not as restful. Therefore, I would recommend this product and think that it is helpful.
