I have a very dogs, one has had absolutely no problems with his sensor, however, my other more active dog has had one lost because of activity, two failures because of water damage, including one that was suppose to be water proof. Otherwise, the power door works wonderfully and gives my dogs the freedom to come and go to the back yard at will. This is controlled by being able to turn the door off at night or when I do not want them to come in from the yard. A great product and I am pleased with it. Paul

The product works as it should. I think it is more expensive than it needs to be. I have purchased a few over time and now close to the cost of a new door and collar. The batteries have a reverse polarity so you are forced to spend more money on batteries. For me, if the batteries were normal, I would spend the money for collars when needed and not say anything negative.

This collar system combined with an automatic door opener has made the lives of our four dogs so much more convenient. They are no longer dependent on us to open doors to let them out to play, toilet, lounge in the sun or come inside if the weather changes. We couldn't be more pleased with the investment in both the door and the collars. We would advise removal of the collar if your dogs are going to swim in salt or fresh water, however the collars are fine with rain and a wet dog. There's a quality gasket seal inside the battery access plate, but just to be safe, we remove collars for swimming.

We use this for our power pet door. 3 dogs & 2 cats use it and love it. It keeps us from getting up & down to let them in or out.
