So I went on a trip this fall to Ohio. The owner of the property had bought 15 new Millenium hang-on treee stands. I had never been in one before and was eager to try them out. I have to say that they are the most comfortable hang-on stand that I have been in. Their full-size folding down seat is like sitting in a deck chair on your porch. The stands are attached to the trees by a chain (very secure) at the top and rachet strap on the bottom. They had very little movement to them when moving around. The only bad thing that I found with them was that I had to get out of the comfortable chair to actually shoot a deer. I would be lying if I said that I didn't doze off a time or two while in them. Yes. I had a safety vest on.
I would recommend these stands every time.
