Works well, but slightly noisy.
*Update!  Talk about gouging I bought this in December for $29, now it's $50! Also the sound gets louder as times goes on.*<br />I use one on the small bathroom to control smell skeptical it would work but it did!  I then got a second one that we move around where needed for smell or sanitation (if someone is sick.)<br />The biggest drawback is the noise...it is very nosey.  It started out quiet but quickly became loud.  Not so loud it's unusable but enough it could be annoying to some.  But over all I highly recommend this product.
