Ownpets Dog Screen Door, Inside Door Flap 12x14x0.4 Inch, Lockable Pet Screen Door, Magnetic Self-Closing Screen Door with Locking Function, Sturdy Screen Door for Dogs Cats

The OWNPETS Dog Screen Door is a lockable self-closing pet screen door designed for dogs and cats. It is available in a 12x14x0.4-inch size and suitable for use with single or sliding screen doors. The installation process is easy, and it comes with clips and bolts to fix it onto the screen. However, the flap may come loose if it is not correctly installed. The door flap is sturdy enough for medium dogs, but larger dogs may encounter difficulty squeezing through the door, as it is lightweight, cheaply made plastic. Additionally, the screen material can become loose with time if too much pressure is exerted. The door lock clips work well and do not protrude or snag anything. Overall, the product is effective for small to medium-sized dogs if installed correctly.
