I have the opposite experience with non-that-brand (that band the only enduring one, and it doesn’t even have lithium batteries).

40k vibes (20k full movements) per minute is at the lower end of acceptable (the speed creates the jets between the teeth), but that is great!

Iirc at some point only one company made such motors (with such speeds for such brushes), first only for Phillips.

Ok, but like … it took Trump of all them bad humans to end free megacorp bailouts?

Man that’s weird in that context.
