I have a single string Black and Decker and a double string Black and
Decker. They both advance string automatically, and work great.
The single string uses string much faster and is mainly used when the grass
and weeds are not very high. The double string unit is a real work horse.
I've used it three times and it still has not used up that first reel of
string. The only draw backs with it is it is much more powerful and quite a
bit heavier than the single string unit, and is a bit more difficult to
control. I prefer it over the single string unit though.
