By cons it has a tendency to stub exit if given the green leaves to eat and it is difficult to débouchonner. The reverse is not very effective. We must stop the machine and return it to remove the cap by hand and the outlet neck is too narrow to do easily.
I removed another star because the ground material is not very late. Often the branches are chewed rather than severed. The volume of waste is greatly reduced anyway and I do not regret my purchase.
