You may not need it every day, but when you need one of these, you're glad you have it. As a shadetree mechanic, I used it to tighten the bolt on a shock absorber - if you know shock absorbers, you know that there's a post that sticks up and it's cumbersome to hold the post and tighten the nut efficiently. An unexpected use that made me love these even more was this: I took the spark plug boots off an engine, and one of the boots/wires were so stuck on, that the wire broke, boot ripped, and I was left with the electrical connection from the spark plug wire stuck onto the spark plug. That connection sticks out past any deep well socket that you would use, so you can't get the ratchet into the socket hole. This tool saved the day. That ONE use made it worth the purchase for me.
