Borrowed this shredder from my mother-in-law who could not get it working properly on her small bits of greenery. I tried it first on some reasonable branches about 1/2 inch diameter, lots of noise but little shredding. Next I tried it on smaller twigs and leaves. Very little shredding and I had expected the machine to draw the vegetation down through the shredder once it had taken hold but the twigs just stuck there with the blade whizzing around. Perhaps the blade needs sharpening but I gave up. Very disappointed. It is now in the back of the shed which I guess is where it will stay.
