My son bought this for me to use when he knew I was flying with our Shih-Tzu to visit him in Florida. He did not know I always carry extra bags for traveling with her in her Sherpa Pet Carrier Medium Black. The first time I tried the dispenser was in the evening using the flashlight; it was a ++++ for me. It is small enough to fit in my pocket, but the flashlight gave off enough light to see the area that needed to be picked up. Plus, I used the flashlight to walk over to the doggy dumpster area. After that it did slip out of my hand onto concrete when I went to turn the door knob to get back into his place. I thought for sure it was broken because I could not get the flashlight to work, but my son put it back together again and the flashlight works fine. Now I put in my pocket before turning the door knob or to have a free hand when walking (the clip is sturdy enough to attach to your leash). I bought two more to have as spares because I like the product so much. I'm so glad he did not know I already had a bag dispenser (w/out flashlight). The flashlight turns off/on by rotating the yellow part.
