Would purchase again

I've had the large power pet high tech dog door 3 years. Continues to work like new. I've had as many as 3 dogs using this door at same time. Dogs learn quickly the dog door because the door opens per their collar when near. Sensitivity can be set as to range of dog near door. There are no drafts around door installed. I put mine in the wall. This collar worn has special batteries. Not greatly expensive lasting 3+ months. Depends on door use. I love this door. My dogs also. My only complaint would be, collars need to be rechargeable. I will purchase again when mine no longer works.
