A member posted this in the "pic of the item you just bought" thread. I bought 6 of them as well and i agree with him. They are AWESOME for the money. We're talking a few bucks for the light. They are fairly well weather proofed, take triple A batteries and so for with using it at least 2 times a night to take the dog out for a month or so it's hasn't lost it's brightness. Super convenient as well with the magnet and hook.
