personally i wouldnt go buying something like that which is coming in from china even tho it says item location is southall if you have to return it under warranty it has to go to china normally, you would be better off buying an optimate or something similar for t he same kind of money far better deal in my eyes,i have the halfords one that comes with 2 different sets of leads so that one set can remain connected to the battery all the time and the 2nd set have crocadile clipsso you can clip onto any other battery if needed and it can be left on when bike not in use like the optimate as well like this http://www.halfords.com/motoring/bulbs- ... ry-charger
