I have a hoist and have loaned it out to friends on several occasions. Friends, mind you. People I know and hang out with/know where they live, etc.
On a couple of instances, said hoist came back missing things. Nothing major, but a lost nut here, a missing clip there. On the plus side of things, I did lend it out once to a friend and he said it was leaking/losing pressure.....so he bought a rebuild kit and rebuilt the ram! It started leaking again soon after, but hey, it's the thought that counts, right???
I can't imagine what would happen if I rented it to some unknown/random element.......probably nothing good!
And you couldn't pay me enough to work on other unknown people's stuff....a quick 30 min. "no problem" project turns into a full day......full day when I coulda been working on my own stuff....
