Query: Not very good

Thought this would be an upgrade over my TroyBilt which was starting to give me some problems after 4 years. Seems rather flimsy and there's a lot of vibration. There's no good way to adjust the trimmer head 90-degrees to trim along beds - and if you do, you can't see what you're trimming due to the guard. The lawn edger attachment has no sidewalk guide. I got my old one fixed, and will likely never use this one.
