i can quite honestly say ive tried / had them all, the cheaper 30 quid ones work kinda ok for a month or so but no real power, the sealy ones are slightly better and do last but forget starting most diesels especially if theres no batt power atall


nothing else works better than the snap on one, i bought mine a few months back for £180 1700 cranking amps it has started everything i wanted it to, i can honestly say if you use one quite often you simply cant buy anything else
