Best Battery trimmer so far but edging not optimal

I upgraded to this brushless string trimmer after frustrations with low power on the B&D 20 volt trimmer. I can say that this thing really rocks with power--close to a gasoline trimmer power. Tall weeds that would bog down my 20V trimmer are no problem for it. Yard is done in half the time. Two downsides: the edge trimming function is difficult to use. The 20V B&D trimmer had wheels to aid edge trimming, but this one just has a metal U shaped bar. Takes some getting used to and not nearly as smooth. Also, the way the trimmer is held is different from most: you sort of use your forearm to counterbalance the trimmer rather than holding its weight with the palm of your hand. Took a little while to get used to but i think i actually like it better than traditional holding position of trimmers.
