I got this with the cats in mind. It seemed fairly well reviewed, and I was getting other stuff anyway. Well this thing barely works at all. Sometimes it makes a bright light, but most of the time I'm trying to make it work at all. Usually the light is pretty dim, and it barely shines across the room. Then it will shine brightly all the way down the driveway. If you need this for a Powerpoint presentation then spend more money. If you don't mind throwing away a few bucks then get this one. It was so cheap it 's not worth returning.
