I bought one of these at AAP for maybe $5-$10. I have had it sitting in my car for months. Today I dropped a screwdriver into the bilge of my boat where I cannot see or feel it sticking my hand down as far as I could. Brought out my handy flashlight with telescoping magnet, extended it, slide it under engine in the bilge and out comes my screwdriver on the first try. I am impressed.
