I've got several, wife's granddad use to own a tire shop, and her dad didn't nave much use for them, so one day while visiting, I noticed all these bottle jacks sitting out in the rain, so I asked if he wanted them, he said 'no', so I took them all home, dumped the rain out, re-filled with hydrolic oil, and I've gotten most of them to work.
I did purchase a very nice Enerpac before that day though, and it is my "go-to" bottle jack.
If I was to make a reccamendation though, I would say buy one that will work on it's side.
There are times you have to move something, and they can be a real tool then!
