Delivery good jump starter rubbish. Followed all instructions to the letter but it wouldn't start the car just about managed to get it to chug. Disconnected put the starter back on charge and tried the following day with the same result. Eventually managed to manoeuvre a second car adjacent to my car in a very tight driveway, connected a set of jump leads borrowed from the brother in law and the car started first time. I now have a piece of useless kit parked in the shed. I bought the starter as I had had a the same problem before and had to call out Green flag who resolved the issue by connecting up a jump starter so I thought I would get one myself to end any problem and save callouts. I was wrong. Should have bought a set of jump leads. Thanks to Europarts for asking for a revue hope it gets displayed
