I bought this due to redoing my back deck. The old deck had rotted over the years from lack of maintenance from the previous owner. My dad came down to help with the deck but he managed to hurt himself while we were ripping up the old deck. So I had to reinstall the new decking myself. I was not aware that this could be done by one person till I was looking around amazon and stumbled onto the BoWrench. I ordered it and got it the next day due to free amazon prime NDA shipping which worked out great since I needed it quickly to finish the deck. And let me tell you this tool is awesome. It is as easy as putting it on a joist and tighting it up against the flooring you are putting in. It allows you to have the extra hand to install decking yourself.
