I wouldn't knock it until I've tried it, but I also wouldn't spend $120 to try it. I would be a little nervous that it would get caught up on the pole some way, causing me to wrestle with it half way up the pole. There are a few guys that I know who are scared to climb...this could possibly be a good tool to help green beans climb their first pole.
