I LOVE THIS THING!Gone are the days of trying to shoo chickens in to the coop-throwing my shoes and obscenities at them at 930 at night! By myself I installed the Pullet Shut door-MUCH easier when I realized the electric drill had a forward AND backwards! I think they took for granted that I had a little more know how than I do when they prepared the directions but emailed questions were answered promptly. Previous posts have stated the $180 price tag as too high. For me to be able to stay home in my pajamas and be able to install this to my existing door-PRICELESS!
