Since purchasing this trimmer, I saw. due to age and health problems, I had tried various devices to make my borders and cutting the grass around trees (fifty ..!) but for me, the heat or rope pulling devices to start, it was impossible ..! (not that we do not understand the devices for garden with electric start, and light ..!) I also bought a cordless trimmer, but not powerful enough it happened ... not even cutting the couch ..! but with this black and decker more soucis..je do a good job. it is light, powerful, has the turbo function, rapide..et when the battery is a flat ... that means it's time for me to take a break ...! really, I recommend it.
