I have had the pullet shut door for almost a year now. The trickle charger failed and I bought one from the Western Auto and added the same ends the pullet shut charger had (piggy back ends?) The door worked like a charm again and they even sent a new trickle charge no cost because it wasn't a year old. The silly chickens unhooked the connectors to the battery and I didn't know about it for a while. I decided to put the new trickle charger on from pullet shut, but the door is not closing all the way. It opens quickly with no problems, but shutting is now like molasses and it's not a tight shut like before. I've been looking around for a different door, but don't want to pay the near $300.00 like before. I'm not too keen on using a string pull door because I've heard too many stories about the string binding up.
My current opener opened as timed, I'm really wondering how it will shut.
