I am going to start building a chicken coop soon and was wondering about the drapery Add-A-Moter model D20? I have seen several videos about how they work and was just wondering about the reliability of the motors over extended periods of time. I have also looked into other ways for automatic door motion...electric car antennas, electric window mechanisms, pneumatic cylinders, power drills, solar and 110. What would be the best solution for someone wanting to do it as cheap as possible. Please give your feedback and ideas...Thanks for any ideas that may get posted!!!
