Bought these keychain lights on a whim and glad I did. I didnt need 5, but for the price, why not. Well, I put one on my keychain, and showed it around and all the rest were gone in minutes. Everyone in the house just had to have one. Its a nice bright light that is great when coming home late and someone forgot to turn the porch light on, poking around in the back of the closet, inside the glove compartment in my truck, or anywhere a bit of brightness is needed. A great buy for a great little product. Thanks
