Review on Hale Pet Doors Wall Model, Double Flap: Ultimate Convenience for Your Furry Friend by Kathy Jones

I looked around for a long time before I came across Hale's pet doors. Our original door lasted 10 years but we moved and it stayed in the house. At first I was concerned that air would seep through the thick plastic vents from both the outside and inside, so I lit an incense stick and the air wouldn't come out in any direction. Just head and shoulders above what's on the market. We just bought a second one direct from Hale - they offer a 10% discount for regular customers and a 10% charity donation for your beloved pets. Good product.
