Weed wacker string life is pathetic

If the string keeps breaking off at the eyelets, that means you're forcing the string to bend too much.

Raise the trimmer head up so that only the tips of the string make contact with the concrete.

When I'm edging, I bump the head three times in a row to give me plenty of sting for edging and I pull the head way up away to keep the string as straight as I can. Anymore questions? I do this stuff all day everyday.
