Compare connected fixtures
Tell us whether a second bowl or dishwasher discharge is affected. State what the disposer itself sounds like, without repeatedly running it.
Assess before replacing
The waste route, outlet and controls may need different attention. Professional assessment can locate the relevant issue and avoid treating every slow sink as a failed disposal motor.
A useful distinction
If water rises in the second bowl while the first empties, describe that relationship. It can help direct attention to connected drainage rather than the grinding mechanism, but does not by itself identify the restricted section.
