Review on SmartDoor by PetSafe - Dog and Cat Door Activated by Collar - Ideal for Small to Large Pets by Pam Hansen

Concept is great but delivery is wrong! 3 big dogs, about a year old with more than a dozen keys! The keys are fragile, large, bulky, the batteries are poorly screwed in when charging. No alternative source. Enter quality, it's quite a profitable system here! Now when I look I see a lot of bad reviews saying the same thing. Obviously the company isn't listening and has no plans to do anything about it. The whole point of getting this system was random and obviously cunning creatures finding their way through my favorite door - skunks and rats. no Exactly. desired. So much for this problem.
