Replacement part that works
I wish the on-off button had the same settings as the original Waterpik Pro's.  This unit is "usually on" as opposed to "usually off" of the original design.  Other than this point, I have no complaint.  I have a broken tube and do not want to buy a whole machine.  This one provides just that repair at the right price.<br /><br />Update: the connector at the bottom broke after 2.5 years.  I think it is still worth the price.
