It is a very simple and reliable design. You need to stop and reload the head when it quits cutting but this takes 30 seconds at the most if you precut your line and keep them in your shirt pocket.

It's far superior to other heads and I'd never go back to bump style heads.

However I'd recommend you take a set of needle nose pliers with you along with precut line. Sometimes the stubs of old line are hard to pull out if they've been there awhile.

What line do you guys use... .95 or something heavier?
