Since owning my model 3 from last November, I was looking for a strong and easy to install/remove license plate bracket. I finally found it and its made by Ottosteer. I normally don't like having the front plates installed on my cars but one of the reasons I bought this was to be able to park on San Francisco streets without worrying about getting tickets for no plates. The other reason is to have it on when passing thru different states while on a road trip. It works really well for me because the bracket uses really strong magnets and you could easily put it on or remove in a few seconds. They are based out of San Jose, so if you are local, you could have them install it for no charge. I just returned home from LA to Pleasanton, and the bracket is very strong and quiet. There is also a retaining screw which you can screw in that will secure the bracket from being stolen.
