My brother, myself, and his helper all tried this tool about a year and a half ago, and we all disliked it. They hated it immediately, but I'm always hoping to find something interesting in new equipment so argued with them that we should try it more, and maybe it works well in different scenarios. They were right. I finally gave up trying to defend this PoS, and back it went to the distributor.
Maybe they improved it since then, though. I hope so. It's an interesting idea.
