Ring Floodlight Cam question

New to Ring and just got 3 floodlight cam and all 3 of them have plastic round mounting plates instead of the round metal ones that I've seen on the web and youtube. How durable are the plastic mounting plates? for the folks that have the same setup. I cant seem to find the metal mounting plates anywhere, contacted support to get the metal ones and no luck. I'd rather have the metal mounting plate for longevity and not worry about the plastic ones breaking.
