Best buy for Lawn and Garden! I love that the battery holds enough of a charge to allow me to whip and trim our LARGE yard (1/3 acre). Fencing around entire back yard, lots of driveway and sidewalks to edge! I'm 63 and have a bad back, but this unit is light enough for me to carry for the 60 minutes it takes me to do our entire yard! I highly recommend this trimmer/edger! Ease of Use The small pop in string replacements are EASY to install, and last me through several uses before needing a new one. Handling Small, lightweight.
