I didn't say anything about any blinking red dots(Another useless waste of $) I'm talking about the auto-door, and I know that costs more than $15-20. On the weekends around here, darn if I'm getting up at the crack of dawn to let the birds out, they have to cool their heels a bit, til I roll on...
The BEST anti auto-door clip I've ever seen. What do them things cost, $300, $400? No thanks.
By using the old manuel door opener, no birds get locked out around here and they sure won't be let out with a fox in the pen.
