On my daughters Mini One the rear drivers side spring snapped, she needed it doing quickly and as cheap as possible as she needed it for her studies at University.
I ordered the springs, they came in minimal packaging within the expected period, they were un-damaged and I fitted them a few days later.
They are cheap BUT unlike lots of other products they are well worth the money especially when you are on a tight budget.
Easy enough to fit if you have the right tools and ability and they look like the originals.
She seems happy enough with them a month on from them being fitted.
