I've used this two or three times since purchase. Seems to do exactly what I expected - works well for trimming lawn edges and getting rid of tall weeds. Battery lasts about fifteen minutes on "full throttle" and that's about what you would expect, I think. If you need something to clear a whole garden or a large patch of weeds, then this probably isn't for you, but for light duties around the garden without having to fire up the petrol strimmer, it's perfectly good. Also, the plastic cutters that you use with it are easy to change. Again, better than having all your strimmer wire getting knotted up.
