A word of warning - don't use it on weeds coming up through gravel, it will break! I use mine on the lawn, & find it works wonders, and seems to bring most of the root system up with it. If you have weeds coming up through gravel, I have a wolf-garten weeding knife, yes, you do have to get down on hands & knees, but it will remove EVERY bit of weed. The weed puller is great if you have a big lawn, just keep a bucket with an even mixture of grass seed, sand & potting compost to fill in the small holes (not craters in my opinion). Pop it in a used bread bag, & snip the corner off is the easiest way I've found to fill in the holes, bit like using a piping bag to ice a cake.
