Bought an electric strimmer from tesco for £15 just to tidy up occasionally. It was useless the cord would snap every few seconds and a real frustration. Saw the reviews on this stuff and thought I'd give it a go. You need to cut off a metre or so from the roll and wrap it around your electric strimmer spool and Bobs your uncle. It never broke once up against fencing, trees, drains and hell I even started cutting the tall long grass and it did that as well. Dare I say it, but strimming is almost fun :)
Well worth the money and a great item.
