Horrid Freight press "on sale" LOL

I've had one of the 20 ton models for a few yrs. and the only problem I've had was if you let it set over a day or 2 the jack won't jack up right away. You have to pump the handle several times then it'll start to move and once it moves it works fine. Maybe just air in the jack?? Not sure. Haven't worked on any bottle jacks to know much about them. Other than that it's not bad and I've really put it to the test on some tough jobs.
