I never had one but a couple of friends did and I checked them out. They are good in my opinion and my friends. I have had the Sams and now the Harbor freight jack. I like the HF
jack also. On my Sams jack the hyd jack went out after a couple of years and I tried replacing it but could not find one that would fit it good. So I did not trust it any more and got the new HF. You can get the HF jack when on sale for about 79 bucks.
But to answer your ? I think the Sears jack is great.
