Bests & Worsts Reviews from Amazon

I'm very happy with this purchase. I bought this so that I could see if there was any stains left in the carpet due to my dogs urinating on it. I have a steam-vac carpet cleaner and wanted to make sure it was doing its job. There are a bunch of different UV / black-light flashlights out there, but this one seemed to have the most LED's for the price. And it takes AA batteries instead of AAA's. So it should be a lot brighter, and the batteries should last longer than other flashlights out there. My results: The flashlight itself is very solid. It's made of metal. It is very bright and does exactly what I want. The beam is focused well. It showed me stains in the carpeting and the couch that I didn't know were there. It's so bright that I didn't have to even make the room completely dark. In fact, you can use this with your house's lights on, although it won't work as well. So it does show me how well my steam-vac carpet cleaner works. I expected that. What surprised me was that it also shows me how well my regular vacuum cleaner works. I see little dots of bright stuff all over my carpet. That's the dirt and lint that the vacuum cleaner missed. Time to get a better vacuum cleaner. The only negative thing I'll say about it is that once you get this thing, you're going to go from room to room in your place looking at everything. And you're going to find everything! It will surprise you. In the end, you may become a lot less happy with your carpeting and furniture, to the point of wanting to go out and buy new ones. This inexpensive little flashlight "toy" may end up costing you thousands of dollars.
