If it's the red one...then I have it and it's adequate for casual wrenching. It will take a bit of trial and error to find the right balance, but once you do it is very stable. ALWAYS lower the jack to use the locks (never just leave the lift hanging and expect it to stay there) and I use the tie down straps if I am pulling tires or anything else that may cause an imbalance.
Other wise, very nice jack, good deal for $99.
