Review on Ultimate Protection: GermGuardian LB1000 Replacement Guardian Sanitizers by Mark Ponnusamy

I liked my GermGuardian when I first got it, about 6 months. I've only read that you buy a new light when the light goes out. Well, my lights didn't turn off, but they didn't help anymore (I can say that because they completely eliminated every dog smell in our house, but they didn't anymore). After lots of research and a frustrating few months of not being plugged in around the house, I found that when the bulbs needed replacing, the light changed color, not that they went out completely. Well I love them again now that I have new lightbulbs! I will order again soon, I don't want to be without it anymore!
