Amazingly, it actually DOES work!
I thought this thing would be a joke, but I got it, plugged it in, and man, it really works. I'm amazed. I have it positioned next to the dog's Wee Wee Pads, and it has completely neutralized the pet odor in my condo. It's a little bit loud (kind of a low-level whirr noise), but whatever: it works.
