Works but not "Whisper-quiet"
I was disappointed as it seems to work but is definitely not "Whisper-quiet", in truth it is very noisy.<br />I bought it for the bathroom where we have the cat's litter-box and it seems to help with the smell but the noise is way too loud.  When I first plugged it in I thought it must be broken it was so loud, until I read the reviews and saw a number of complaints about the noise. Others describe the noise "like a computer fan" but it's actually much louder; I have a full tower computer on my desk and I can hear the noise from the GG-1000 across the hall and in the bathroom. At night it's the loudest thing in the house.<br /><br />The GG-1000 would probably do fine in a office with lots of other noise (or where you want a "white-noise generator" but don't get it for your home).<br /><br />I'm returning it today.
