You bet popsgee,
Don't get me wrong. I mean, there are way more durable lights around than those $1.00 lights. But for the money, you can afford to have them stashed all over the darn place ..... purses, glove boxes, first aid kits, tool box, night stand drawer, etc, etc, etc. Oh yeah, and your keychain too.
You lose one, not a heart breaker. Someone needs a light to get to their car in the dark, give them one and let them keep it. I'm tellin' ya, people really do like them. Especially in the winter when you can't see where your car key or house key goes.
Get at least 40, trust me. Family, friends, UPS guy, bank tellers all the folks throughout the year who help me get at least one, generally two.
