What's your favorite automatic door opener for your chicken coop?

I've been investigating automatic door openers for my chicken coop and have to make up my mind very soon. Do any of you have any recommendations?

I have and love the Ador. It operates via a lantern battery.

I always recommend the Pullet Shut door. I have had mine for over 5 years and I have had no problems with it. It's a well made, dependable door.

I use a ChickenGuard since I wanted something battery operated, with a timer option, that didn't swing open/out (don't have the clearance for it).
