Great addition to the bag of tricks - 03/26/2017
Reviewer: Mike Carter
I use this pretty regular. I often have inexperienced groundies helping me and this lets me take over the load control in the tree after the cut and they can focus on managing the load. It can be a little work pulling the rope through even when unloaded, but I usually have the groundies do that. And I don't have to worry if they loaded the port-a-wrap correctly.
Fantastic option for rigging - 11/28/2016

Fantastic for light to medium rigging. It reduces forces applied to the tree, as well as offers the invaluable ability for the person in the air to control the piece being lowered. It's very simple and easy to configure. I know I'd buy another one the same day if I ever lost the one I have now.
Bingo! - 09/09/2016
This tool is the answer when I have a few heavier pieces to lower and the guys working the ground don't want to install a porta wrap, and I HATE trunk wraps. It does restrict yor ability to lift and it's significantly more difficult to haul back(friction both ways). With all that said its a great tool to have in your bag of tricks.
sweet product! you better get one - 05/06/2016
Got this the other week and been using it none stop. Great for when you have an inexperienced groundie that can't seem to let just one piece run a little now I have all the control in the tree. Very great product. Only down fall is the rope is very hard to pull back up when you go through all four holes other then that I am very happy I got this for my rigging bag.
TREE STUFF FOR LIFE!!

Reviewer: Michael Minardi
This is a great addition to your tool box, and a good way to add a margin of safety when you have to rig a tree with structural problems, and want to minimize rigging loads in the canopy. My groundie was very impressed with how smooth and constant the friction was, and that he could move around as much needed to receive pieces. This will be a go to piece of gear. I did convert the standard tail on it to a whoopie sling, much happier. #ThunderWhoopie
