Lifts like a champ. If that's all you want to do, you're golden. Lowering is a different story. Instructions caution that jack may drop load if under 50 lbs. I tried a number of times with a load of more than 100 lbs, and was unable to find a way to lower the load smoothly without dropping and without fail. If you hesitate between clicks, drop. If you go too high or too low with your stroke, drop. You just never know. This is not a precision instrument. Bear that in mind, and use extreme caution if/when lowering a load that must NOT be dropped.
