Query: Great Light

Have been using one for many years on my keyring. Very small and easy to carry. Provides good light for finding pathways, keyholes, and other needs in the dark. Batteries last me 2 or 3 years and are easy to replace-can be bought cheaply on line. Just bought a few more for gifts. I have used others like it but this one has been the best.
