Rated 5.0 out of 5.0 by Excellent Product & Value I love that this arrived at my front door. It only took 2 ex husbands to install it and only cost pizza.. Lol June 10, 2014
Rated 4.0 out of 5.0 by Good security, but lacking as a screen door! These doors weren't too difficult to install, however, I say that as the girl who sat back and watched her husband and father install them. So for ME, it was effortless. For them... Minimal swearing, so it couldn't have been TOO bad. I think the only problems that they had were more related to the crookedness of our house/door frames. These doors have unique (giant) one way screws to install the frame for the door, meaning they screw in easy enough, but there's no way to screw them out using a screw driver. So get it right the first time, or you'll be using pliers to get the screws out, which can be time consuming. As for the doors themselves... These work well as security screen doors. The screen part is metal, so it can't be punched or stabbed through easily, like regular screen doors. They have 2 holes, one for a lockable door knob, and one for a dead bolt, which gives you two times the protection. I would feel safe leaving our front door open with the screen door locked, even if I was in another room or another floor of the house. So the feeling of security is there, without a doubt. There are a few drawbacks to security screen doors vrs regular screen doors. For example, the holes in the "screen" part of the security door are about 3/16", which is plenty big for ants, mosquitos, spiders, bees, and more than likely, stink bugs to get through. My way of overcoming this challenge is to purchase a roll of regular screen, cut it to the size of the door, and fasten it to the door using strong magnets (since the door is metal). Maybe not the best way to handle this, but it'll do for now! The other issue I can see with these doors, as compared to regular screen doors, is that there's no way to "winterize" them, since there is no glass involved. Regular screen doors typically have glass to replace the screen during the winter, but these doors don't have anything like that. Overall, I'm satisfied with this purchase. We bought these doors mainly for some added security, and I feel like we have accomplished that goal. April 26, 2014

Rated 5.0 out of 5.0 by Excellent Security door at an even better price! I was thrilled to find the door on sale for almost 40% off!!!! The Security Screen door is easy to install and is beautiful to look at. It will last a long time and is kid friendly! Smudges come off easily and there is no screen that can be damaged! It was on sale when I purchased it! I am very happy with it. May 14, 2014
Rated 5.0 out of 5.0 by This screen door is working well for us. We are looking forward to being able to leave our regular front door open at times. This screen door is working well with keeping our dogs in place while we are able to have the main door open to the fresh air. We have not had the opportunity lock the door for our safety but I believe that it will give us more comfort. I really like the way that we were kept informed as our order was processed and the door shipped; we were also pleased with the service when we went to pick up the door. July 28, 2013
