It's a bit odd reviewing something like this because it is what it is. I'm only doing so because I don't want others to make the same mistake as us. If you were buying this to replace a shorter mains lead, it wont. It doesn't have a mains plug at one end and a Flymo connector on the other. It is (as the name of course suggests) an extension lead. You connect one end to the Flymo and the other to the end of the original mains cable. I figure I'm so used to calling mains leads with a mains plug at one end and socket at the other (incorrectly) and extension lead that I made this fundamental mistake.
Still we have a very long cable now. I'll go and do the neighbour's lawn to....
