Adequate
Just about adequate to get the job done.  Better than most.  I've tried at least 3 brands. This is the one I settle for because it works adequately. I have another as a backup but this one cuts better than it. None are strong enough to efficiently do the work, so I settle for this one. Charges OK, and holds the charge.  Definitely read the directions on how to remove and reinstall the blade.
