Product review (3 stars): Impeller shaft broke after 3 years
This pump worked as advertised several years but, as others have written, the plastic connection between the impeller blade and the magnet that the motor spins broke.  This caused the motor to stay running but not pump anything.  No harm done as I have a water sensor on the floor that alerted me to the overflowing reservoir.  Tried using epoxy to fix it to no avail.
