what add is that? the link you posted isnt big enough to read. I have a grizzly climber that ive had for a year now. Its not bad especially for the price. It's kinda squeeky when you shift your weight when in the tree and you will need to add some straps so it doesnt make too much noise when you are walkin through the woods. This might be a different one though, put abetter attachment on here and i will let you know.
