i am on my 4th craftsman aluminum racing jack, they are junk as far as i am concerned, and i dont abuse them either, maybe 3 lifts on the first one, and it started making terrible screeching sounds under any load (like the weight of a person)... the next 2 just wouldnt maintain pressure after about 6 lifts each...
i havent picked up the fourth one yet, but im hoping this one lasts a little bit longer for me!
