I can't believe that she works with this clothing. That's a tripping hazard and will catch the chain at the least opportunity. But that's good for the show and the audience : she's on the TV, mind you !!!
Poor shape and poor technique, chain completely dull (on an other vid a little longer, she gets only smoke on a 4" limb), she want to help but she doesn't know what she's doing. Homeowner level, and not a good one. I hope really not, but she could very well be hurt.
