Why did you choose this product over others?:Worked well even though my model of waterpik isn't mentioned in the description of what these will fit. They fit fine.

Perfect fit

I can use my waterpik again. Great value, easy to fit.

Pushes firmly into Waterpic valve hole and stops water running out while filling

Perfect part for my waterpik, but will I need the 5 spares?Would have been better in a bundle of service parts, like a new wand or something, something you might need each year or something.
