I bought this back in 2010, so I figured it was time for a review.  I'm not a gear head...  But I've changed enough flats in my time to know that the cheap and DANGEROUS scissor jacks that ship with nearly all vehicles today aren't worth a crap.  I wanted something I could stow in my trunk for emerengcies.  I've used it three times in that period and it's made an otherwise pain in the rear-end job a snap.Torin is a chinese brand, but unfortunately unless your spending hundreds or even thousands, American made racing jacks are hard to find.  Their quality control from what I've been reading seems to be hit and miss.  But mine has been fine.  Materials and machine work don't feel cheap to me.  Everything is tight fitting and works as it should.  The weight is perfect for my use at under 30lbs.  If your using a racing jack on a garage floor I don't see why you sould care if it's 100lbs as long as it rolls.  But lifting it out of a truck...YOU CARE!  It's compact size leaves me plenty of space in my Lancer's trunk.  The two section lift and release handle is perfect for this too.  Make sure you bleed this thing as the included instructions state when you unbox it!I've lifted my Mitubishi Lancer, my friend's Toyota Camery, and my father's F150.  It never complained even once.  The lift speed was fine with me.  I don't remember how many pumps it took, it wasn't 3 but it wasn't rediculous either.  People make too much of a fuss over that (unless they really are a race crew, in which case SPEND the money and buy American!)  Most recently I did lift the F150 however I really would recommend a bigger jack.  The capacity was okay more or less.  But the height was a challenge.  An unloaded half ton is right around 5500lbs, one corner should be within rate spec, but your pushing it.  Do yourself a favor and invest in a 2.5 to 3.5 ton rated model with better reach and a bigger piston.One final word...  And this really should be common sense...  NEVER and I mean NEVER craw under your vehicle when up on a jack.  Buy some jack stands with nice large base pads and a few wheel chalks!  And make sure it's solild before you get underneath.  I've personally been there when a vehicle comes down unexpectedly.  No one was hurt but that was pure luck!
