I own two of them (one for each house). This is a powerful trimmer. Starting it each time requires a firm grip due to the kickback. I use it 80% as an edger, 20% as a trimmer. Every other time I use it I need to replace the line - it does seem to go through line quickly, and to that end I bought a huge roll of line to keep costs down.The edger guard (the metal piece that is meant to help keep edging even) assumes that the grass is about 1" away from the sidewalk; my grass is adjacent to the sidewalk and that guard is fairly useless for me.I have not (at least yet) had the problem of some plastic piece breaking that other's have reported. I owned one of the two trimmers for one year, the other for two months.
