A lot of people may have difficulties placing a console - they're not the best shape sometimes, you don't like to put them on a carpet/floor for obvious reasons and yet they do stick out a bit on a shelf or whatever. This allows you to have a fitted bracket on a wall (behind the TV probably) so it's out the way and not on the floor so can't get kicked either.
In the box are all the fittings from wall plugs (ahem "rubber stopper") to the screws which one would expect (nothing was missing as per the instructions itinerary). Actually, on that note, the instructions are really good with colour pictures showing you what to do and as said, the list of components clearly listed and identified.
The actual bracket has foam cushioning on the side where the console will sit acting both as a "grip" and a non scratch surface which is nice (meaning you also don't have to stick them on yourself) and as the description says, it will allow air to get to the console keeping it a touch cooler as such.
Handy to have, gets my console out the way (it was next to my printer - don't ask) and also means it's safer as no-one can knock it over (it's now behind the TV). The additional fact that it works with all 4 console variants is great as well (well all 4 PS5 types anyway). Nicely done.
