We have been dealing with this door for about a year and regret ever buying it!!! Here is our story.... we live on a mountain and wanted the ability to have our dogs let themselves in and out while we are at work during the day. We also wanted something that would let them in without letting in wild animals. We thought this was the perfect solution. We bought the pet door, a new house door, three collar sensors and hired our handyman to put it in. At this time, we have spent well over $1,000. Then, the door wouldn t open sometimes, I called customer service and they said the sensitivity too high. What!!? How can it be too high if it isn t opening??? Anyway.... I ve made calls after calls over the last year because the door wouldn t work, or the sensors would break. They ended up sending a new door. Same problems. They would replace sensors but the part on the back to hold it onto the collar would break....over and over again. We would have to search through the yard to try and find the thing. We were hoping this would make our dogs day more enjoyable but they would get stuck inside or outside....which is unacceptable!!!! So we finally spent more money on another doggy door and house door. More money down the drain. If you buy this door, save time, money, and a year of FRUSTRATION by just throwing it away.
