good power!
Beats gas trimmers hands down. No gas mixing just plug and go.

This had the features that I wanted
I just bought this because it had the features that I wanted: dual line trimmer head and rotating trimmer head for easy edging. It is a powerful machine and works well. The assembly instructions are somewhat sketchy but ultimately it goes together without much trouble. It was a bit awkward to use at first because I am not use to this full size trimmer, but I expect that it will get more comfortable over time.
