I have seen many commercials for these velcro-mesh screen doors that you can just walk through. It keeps the bugs out and your pets can go in and out without you opening and closing the door over and over and over. (Can you tell that is what we have to do?)
I always wanted to try one when we moved (we used to have doggy doors so that was great). So I finally got this Mega Mesh Premium Magnetic Screen Door.
We are currently renting our house, so we cannot have anything that is permanent. This is perfect!
It was easy to install. When we move, we can remove the velcro from the door frame, and then buy new stuff from Home Depot or Lowe's, to use it again.
This particular magnetic screen door has individual magnets sewn in - it is pretty sturdy!
Be sure to measure your door before you order. And make sure that you install the velcro tape in a straight line.
