Works as Advertised
I give this sound conditioner less than five stars because I'm not convinced that "white sound" is as beneficial as I thought it would be. The product works well. There are no problems with its operation though I've had it for only a couple of weeks. If it has a design fault it might be the limited volume control. I got the SleepMate my benefit but my wife is a bit irritated with the sound. To compensate I placed it under a bench at the foot of our bed. The tone and volume control range is quite broad but a couple steps down from the low volume range would be good.
Rating: 4 stars
