We have about ten fruit trees, even picking the fruit can get you scratched up- this tool works very fast to wipe those small branches away.
It took less than an hour, half were high and needed a ladder. It eliminates the danger of a regular sized chain saw using a ladder.
My only wonder is, there's no compartment for bar/chain oil, so none EVER needed? When done, I put a few drops of WD40 on it, just hoping for a long life from the $14 chain- no big deal.
