I when I come to use the strimmer int he garden, I spend more time
taking it apart to get some more line, than I do strimming. It would be
quicker using scissors.

This is true for every strimmer I have ever owned.

What's wrong? Is it me? Are there any tips? (I never see the council
workers changing strimmer wire all the time...)
