Yeah, I like keepin’ it neat.
I’d start with the Mechanical setting since that’s what you have, but you can play some more with Digital and see what works, particularly since you mentioned the rapidity of the ding-dong! sound in another topic and wanting a little more time between the ding and the dong. Since Wyze actually advises trying a Digital setting on a mechanical chime in one of the Help Center troubleshooting articles, I think in the end it’s going to be a matter of settling on what produces the most pleasing result for you.
