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

Everything is fine. They lock and unlock the door until the battery dies. they DO NOT REPEAT, DO NOT OPEN OR CLOSE THE DOOR AUTOMATICALLY. I should have read the description better, that's my fault. The locking and unlocking process also takes too long for impatient dogs and is annoyingly loud. Unlocking the door is so easy with the buttons on the door itself as my poor dumb dogs keep bumping into the damn thing before it unlocks or startle at the noise. On top of that, these things are so bulky that my dogs want to chew on them. Actually mutual (unfortunately that's why I'm not returning them. Sigh) and eaten something to spend if you have more than 2 or 3 dogs. as a foster family, he is also frustrated that only she is allowed to eat. Add 5 dogs. Period. Yes, I know any sane person would have no more than 5 wigs. but of course mine change when they're rescued and adopted so again it's pretty much useless. All in all I have nothing to complain about (well apparently that's not true). They do what they say but don't do what I need them to do. But since PetSafe is a reputable brand, I'll be nice and give them three stars (I was going to give them one and a half).
