Good combo set for a DIY mechanic. Fairly easy to use. Jack works well and jack stands hold the specified load easily. As another reviewer mentioned the max height is 15. Per the instructions I did the break-in procedure with the jackbasically raising and lowering the jack with no resistance. The handle is removable and serves to fit into the female sleeve to lift the jack, and then can be moved to fit into the male sleeve release valve. For those who never owned a hydraulic lift, the release valve on this one functions similar to a screw, where you tighten (i.e. close) the valve to be able to raise the jack. Unscrew (i.e. open) the valve and the jack lowers. To close, just turn the valve clockwise until it stops, then a hair bit more, do NOT over tighten like a nut. This valve does NOT need to be over tightened. I was a little worried that the jack would lower too quickly, as another review mentioned. After using it, I can see that the release valve is very sensitive and if you open the release valve too quickly and too much, while under load, the jack will unload quickly and your car will come down violently. Solution: open the valve slowly. VERY slowly. The trick is to not over tighten the valve. If you do over tighten, you'll have to apply extra force to open the valve and that's when you will over compensate to break the valve open (similar to an over tightened nut), and open the valve more than it needs to be opened to release the load. You can't just turn the release valve while your standing up and expect it to come down gently. Kneeling down, I use an overhand grip on the middle of the handle, while holding the end of the handle with the other hand; then very slowly turn the handle (unscrew the valve) incrementally. The valve is very sensitive to movement. Practice with the lift unloaded. If I had to use it professionally everyday multiple times per day I'd go with a different lift. While it's not perfect, for the sale price and for light duty use, it's a great deal for me.

I have purged it several times per manual. Will jack up a car but slowly drop it. Even with no load it drops with a few hours. Do not buy! Took 2 years to happen.Sears is saving money by manufacturing in China but slowly losing customers.The only thing made in the USA are the tools and guaranteed for life which I buy. Once that is made in China I am done with Sears. I had a sears jack that lasted 20 years or more but that is when it was made in good old USA.
