I bought one. Yeah, I know, it's an infomercial tool, but it's better than a poke in the eye with a sharp stick!
Bought it on Amazon.
It actually works pretty well. I turned a big pile of branches I pruned off the trees
The pile of branches is now neatly tucked away in my municipal utility district approved trash can.
You aren't going to cut down any trees with it, but it's not intended for that anyway. Well, maybe a wayward china berry sapling.
It is reasonably well constructed, although the advertised self adjusting chain tensioning system doesn't actually self adjust without some assistance.*
Pruning is like eating Lays potato chips. You can't just eat one.
Before you know it you've got a massive pile of branches. The pruning is the fun part.
The branch cleanup sucks. Less so now.
Aside from the chain adjustment, the only other downside I found to the tool was the lack of an air conditioner to keep me from perspiring...heavily.
