I have a an old Porsche which even when on a trickle charge the battery does unfortunately go flat. The bonnet release is powered by the battery. The Clarke Heavy Duty made this so much easier than calling out the AA!. Put on charge each month until I get the green light. Hoping this will last me many years. Just what I needed. Great addition to the garage tools.

We bought this item as some of our vehicles sit for long periods between use. Used to start our old defender with completely flat battery, Land Rover fired up first turn of the key. Brilliant bit of kit. Definitely buy again if needed another one. Great service from Dundee depot.

We had a problem with damage to our original item, I had to photograph it and send by e-mail back to the site. Once that was done they quickly picked it up and despatched a new one. The whole process took a week but we now have a good functioning item.
