I've had mine since 2014, not been used as much recently but before covid we we're going nearly every weekend, if you go more than once a month it pays for itself.
Will say that we used to try going anytime of day but due to parking and the age difference on later showings, I turned into a old man and we used to go for the first Saturday morning showing, less people unless it was a huge release and people there who generally enjoy films and know how to keep quiet whilst it's on and not talk or be on their phone.
