never used one, but I have been thinking of getting one. Seems likea great idea. I hunt a farm is southern wv and every tree seems disformed and I think this product would work for me...Sorta steap in price for me though..many good hang on's for less than a 120 dollars out there. if you get one do a good review of it on here. I bet it might be hard to hang in a tree.
