Purchased door armor max kit. Installation was pretty simple. What I found though was kit included 12" pry shield but not the door shield (sold separately) which is used in conjunction with pry shield. The door shield is a 4" x 3/4" x maybe 1/8" thick L shaped piece that mounts to door and slides behind pry shield to prevent pry tool getting between door and door frame. I happen to have some heavier aluminum angle so i made my own piece for door. This kit should be a must for all exterior doors and I highly recommend it. Just remember to order the pro door shield also when ordering kit. Delivery was very quick.
