The product is ,not better than expected ,yes it works and starts the car , but there is a strange noise after the engine has started, like the freewheel in the drive dog is sticking or dry ? It gives off a high pitch screetch after the engine has fired. As its such a pain to fit Im hoping the noise will go away with time ( my customer has not complained yet ) but there is something wrong with the one I had ! ( I could have had the bad one in a batch ! ) On the bright side It does turn the engine over fast enough to start the engine as the old unit was running at about half speed.
