I decided in this case deliberately for a low-priced model. The reason is simple. My / our previous jack was purchased for approximately 30 years ago +/- 10 times spontaneously from my dad in discounters. So many wheels were changed over the years and other work done on the car and the always oohen any problems. From construction and techn. Functioning just like this and probably most car jack. A simple, old and armored principle.
If, like me, will attaches the jack normally 2,3,4 times a year you come so absolutely clear. Processing, material and surface finish effect not cheap and absolutely appropriate for the price range. All fittings and wheels / rollers stuck. The lifting mechanism works perfectly without any interruptions. You do not need very many strokes to maximum height.
Underscore a solid part at a good price and if you consider that you have 2 years warranty anyway, I see no problem anyway. Who, of course, screwed a lot and every day a jack needs ought to spend more. One should always know what you need, then buys and can be expected of them.
