“The quality of parts was good.
However in a kit of seals for a jack I was surprised not to find the cup/bucket seal for the main ram/shaft/piston. Fortunately the old one in my jack was still serviceable (hope) and the small one for the small piston was included ( old one damaged beyond repair) so I have got it working again. The part definitely should have been there and then I would give you 5*s”
