A ram will open the door, it is just going to take a lot of strikes. Much better than just your stock door jam. The most important modification are the 3 inch hinge screws. Right now if I am breaching a door and after three or four hits the knob side wont go, I immediately go to the hinges where its held usually by 1 1/2 inch screws. Seems like a good product. Could really cut down on back door kick in burglaries.
I recently saw this on Amazon too and have strongly considered ordering a few kits for the front/rear/bedroom doors of my home. Paired with a door bar and longer hinge screws (as already mentioned) these products seem to at least offer more time for home owners to "prepare" for an oncoming attack if someone attempts to invade their home in the middle of the night, etc.
I saw this Strike Plate Lock being advertised on social media recently as well. Never imagined that such a relatively simple looking device would hold up to that many door kicks; in theory, at least.
It will work if someone is trying to kick their way in. Its pretty unsightly though. Also in the demonstration the frame is not secure and is actually allowing for some give with each kick, cutting down on the kinetic energy being delivered to the strike plate.
A number of years ago, I was involved in some tests for the National Crime Prevention Institute which graded locksets as to their resistance to forced entry. We found that when a door was kicked, a security strike with a wrap around lock reinforcer would make it extremely difficult to penetrate... at least by the kick type of attack. But we were using a solid core wood door slab with no glass as our standard attack door. We found somewhat similar results by simply attaching the strike with 3.5" screws (into the Jack studs).
There is no doubt that a door-- more preferably a metal or solid wood door--would be very difficult to kick (as shown in the video) with this product installed. If you can get past the esthetics, it should be considered; but hollow core, French or wood panel doors will yield a very different result. There are also many other ways to attack a door that one needs to consider if a higher level of security is desired.
