Bests & Worsts Reviews from Amazon

This thing is so good. It shows every single stain over the years where our dog peed when he was a puppy and still having accidents on the carpet. We thought we cleaned but you can clearly see all the spots. It also shows where dust is hiding that you don't even see when the lights are on. So in conclusion, this UV light is almost too good. It shines brightly over a large area at least 6 feet away. Now I can never lie on the carpet again cause i know where all the invisible stains are. They should sell this as a bundle with a carpet steam cleaner. Ordering two more as gifts. Haha!
