My trusty Halfords version finally lost its grip on valves after many years service, and a single barrel replacement from Asda snapped a rivet on first use(less). So looking to Amazon, needing another urgently as my car rims leak, I waited for delivery. And waited. And waited. It took eight days from placing the order, without a car. So once it did come, first thing was to try to save my alloys - and wouldn't you know it one of the barrel welds snapped under the paint on first use. Had to strip the working remains of the three pumps to get something that works now, mostly the original one with brass joints rather than cheap plastic. No stars here I'm afraid, not even the one the rating system needed to work.
