The service was very good as I had never been disapointed using Amazon the delivery was fast, the instalation very easy but the product does not work property without fixing first it keep on coming down every time so I have to put a hook on top to keep it on place. Second I have to nail the velcro to the frame and third every time the dogs go trough it the magnets never come together so I have to pin the to pieces with clothes pins, after that It gives me some protection for the flies but sometimes even with the pins the 2 magnets on the top do not come together and still have to doing by hand. The idea of leave the door open while the dogs are home alone is still just an idea.
