"This seems like a solidly-built little trolley jack and it was able to lift the back end of my heavy campervan with no trouble. It is compact and this means its range of motion is somewhat limited: I had to pack it out with timber to make it raise my van enough to be able to change a wheel, for example. However, it should be ideal for use with a car.
The cup diameter is very small and it is worth padding this out as well to avoid scratching the chassis. I don't know whether it's possible to buy a wider cup, but it is held on with a split pin so should be a cinch to change.
My only criticism is that the pole is a little flimsy and bent under the increased moment of force required to reach the top of the ROM. On the whole, though, for £30 it is quite a useful tool to have in your garage, and is a step up in terms of speed, convenience, stability and power from the useless scissor-jacks that come with most cars."
"On opening the box I was surprised to see how small this jack is, whilst it being ideal to change a wheel or carry in the boot of the car I believe it is not man enough for more serious work, i.e. lifting the whole of the front of a car by the main cross member. The lifting saddle is very small and could be made more substantial."
