not for quiet spaces, but still useful.
i'm still on the fence w/ this product, but the husband likes it.  we bought it while on stay-cation in a stinky condo.  too noisy for the bedroom.  did not work on the foul odors in there, but we  brought it home anyway because it was affordable, and we wanted to give it a fair chance.<br /><br />we keep it near the stairs (kind of below them) by a bathroom, the 'pantry' and the back door.  the musty, funky, moldy smell is GONE from there now, and it gives a nice light to the dark walkway, but i hear it when i'm nearby and it is annoying.  a high-pitched hum...<br /><br />UPDATE:<br />After several weeks, I gave it to my Dad, who is hard of hearing and surrounded by outdoor free-range chickens and their feathers...as far as I know, it is working well in his small space.<br /><br />Meanwhile, the mustiness is back under my stairs...will have to keep searching for something that works well over there.
