Love, Love, LOVE!
LOVE the Autoslide! Bought it for our dogs when since a single "normal" dog door wouldn't work for our large Newfoundland and our 2 smaller 30lb dogs.
Install seems overwhelming, but ended up being rather easy.
We had some issues with the accessories we ordered - wireless microwave sensor doesn't work with the pet channel. Customer service helped us get everything figured out and switched to a better option for us.
