I found this very handy Review by Abigail Emmerich
Quality Value Price
This door opener has been a life saver and is great for more than just our pets. The install was fairly easy and did not take to much time. I honestly have not seen to many reviews on this product but wanted to attempt to try it out. I purchased it and it came in less than a week. I had taught the animals how to use it and that too did not take much time because of how they let us know they wanted to go out was by standing next to the door. At first my pets were confused but now it seems like second nature that it opens for them. We recently had an outdoor gathering with a lot of family members and I was bringing out food constantly with my hands full. I am not the most coordinated person, but this helped me out so much while I was carrying everything. I also have the key chains and one of our grandmothers uses and electric scooter and did not want to get to close, so by just pushing the open button on the key chain from the kitchen made things easier on her and I. I have found more uses then just my pets with this door opener and I am extremely glad I did not just go with a dog door. I believe with a family like mine this could be so very helpful and hope people find this review helpful. The only issue I had was when I was learning it and I placed it on pet mode. I didn't realize it and got a little upset that it was not opening all the way. Now that I know, it has given me no issues and works just as I had hoped.
