First of all I love the Coslus Water Flosser. This tip and the tablets are amazing. Along with getting the benefits of flossing, your breath is minty fresh. I have these on Subscribe & Save so I never run out!

Fits perfectly. I actually prefer the clear replacement heads. I wish I could purchase a clear water flosser.

I like my previous model better where the water tank separates from the top part. I can clean it better.
