Rated 5.0 out of 5.0 by Wonderful for the Price I purchased this door for my mom's house and not only is she happy about it so am I.For the price it was a great buy and it looks good.Once again with the help of Home Depot I have made a good choice. April 9, 2013
Rated 5.0 out of 5.0 by Read reviews with a grain of salt. I have purchased and installed several of these doors and have not been unhappy with any of them. I have been reading the reviews and while I don't ordinarily take the time to write them myself I thought I'd address some of the concerns listed. There were a few remarks about the lockset/deadbolt not being included. I think the desciption and pictures adequately indicate that they are not included. I think the majority of people would rather choose their own color and style as well as brand so they can key the locks to their existing house keys. There were quite a few people that mentioned this door is more than 36" wide. That's not actually the case - the door with frame is more than 36" as it should be. This is not intended to be mounted flush inside your door jamb, it should be mounted to your trim. One reason for that is that the frame can truly be screwed into structural wood instead of just the door frame. To the folks that had a problem with the security door knob hitting the regular door knob, one solution is to simply reverse the deadbolt and door knob positions on the security door. If clearance is still a problem, then that is an issue with the construction of the main door and not a fault of the security door. Overall, these doors are great and do provide a little extra security - ostensibly the reason one would buy a security door. Installation, if the instructions are followed, is straightforward and relatively easy. as a hint to help reduce the noise these make, I have been known to place a piece of foam weatherstripping on the metal flange that covers the locking latch and extended deadbolt when the door is closed. It doesn't completely stop the noise but it does reduce it significantly. October 3, 2013
Rated 5.0 out of 5.0 by Awesome Pretty hard to put up but got er done. Love the quality of the screen very heavy duty. May 6, 2014
Rated 4.0 out of 5.0 by Looks good and does the job It took longer than planned to install the door locks, but other than that, it went smoothly and is doing the job. January 21, 2014
Rated 4.0 out of 5.0 by Very good value Door was made very well and was surprised at the level of quality for a lower end door...If you need security and dont want to spend big bucks I would go with this....Gonna get another for basement door now.. June 11, 2013
Rated 1.0 out of 5.0 by Improperly aligned door frame I gave a 1 score for each category because none of these count without a functional door. Spent additional time installing the door handle and dead blot lock (not included by the way!) and upon installing the one-way screws for the door frame I discovered that the door won't close flush with the frame due to these screws sticking out about 1/4 inch. Now I have one-way screws, which cannot be removed, preventing the door's proper installation. Called the store...we will see how much help they will offer tomorrow or maybe the next day...........

Rated 1.0 out of 5.0 by not a good buy The door does not come with a screen nor do they come with glass which is not expected. The mesh screen that is attached does not protect from bugs...a bird is not able to fly in but any type of fly, bee, or any other bug can easly get in. You definitely don't want to leave the door open to allow the air to come in. It did not come with door closures or door fixtures such as locks or door knobs. Spend more money and get a better door!
