Anybody have any experince with the Hammer (wall/ceiling mount) bow hanger?

I know I COULD make one for less money, seeing as I have a wire feed MIG welder out in the garage, but I have only one functioning arm for several more weeks/months, and we are being over-run with bows both at the house and mu office at the Church and Mrs. Squid has decrred that we need to do something about the situation, ASAP.
