Pros: quieter, works great
Cons: battery could use a little more uumph
We bought this trimmer about a year ago, it works just fine and we have had no complaints with it. It easily switches from horizontal to vertical cutting and back. We happened to need it one day when the battery had not been charged, so we used the compatible battery from a friend's power drill that was here- wow! A little more power and those stray blades of grass just fly off, did actually make the task go a lot faster. We don't have a ton of edging to do, so it was more a novelty for us than anything we would actually consider buying a new battery for.
