I bought the door closer to our office door. In winter it is terribly cold when the door remains open. I had earlier attempts a cheap product, but that did not work. Responsible for the open doors, two dogs that are happy where their people are with us. Because it not to make the doors behind him, the door closer came into play. He is serving very good, but the spring is very strong and you can not change this power. You have to press very strong if you want to get open the door. Cats and our medium sized dog can not raise this force. As I said, you can not adjust the strength of the spring, one can only regulate how fast or slowly closes the door. In a sense it was a bad buy because the dogs now can not open by itself the door. But I keep looking, maybe I'll find but eventually the right product. 3 stars, because the product is very poorly described and I could not know by how behaves the door closer. The installation manual is also not a deal breaker, without Google we have the mystery of the settings can not solve.
