My exwife actually took my sound machine that I use for a white noise, she is using it in her therapy practice as money do, to prevent their clients from being heard in session. I don’t know how good this machine has yet, it is a perfect copy of the one that she took from Hammacher Schlemmer which I have had for 17 years, I doubt this one will make it that long… Without any further information I would just have to recommend buying one at Hammacher Schlemmer

I run this for about 12 hours a day. Worked well out of the box, no motor problems, no vibrating.It is NOT that loud. I have it right next to my head and while the sound is obviously soothing and masking I can still hear my husband laugh in the living room.

Unfortunately I now work remotely on the phone and my bird is a relentless screamer - the two are a terrible mix. My house is one story so there is no getting away from the noise he makes. This contraption didn't even put a dent in the sound. I think it works well otherwise so I will be keeping it - I am a fan…
