I ignored the reviews and bought this trimmer, the price was hard to ignore and if it turned out to be a mistake I would try to return it or just junk it.After a month this has performed like a charm. Plenty of power, battery lasts at least 30 minutes and the small foot print is not an issue for me. I cut the big areas with my lawn-mower.It is essential for the handle to be seated properly or else you will not get full power, just a tip when you snap things together upon assembly.Replacing the string is easy, but it in bulk and wind it yourself, not difficult at all.I have trashed by gas powered trimmer since this little guy does all I need it to do.Good performance for a low price. BTW you can use a stronger thicker line with it if you desire.
