No nubs.

"This product is not for you.  It's for people who don't have exceptional oral hygiene habits."  

YES!!!

My morning "walks around the block" are paying off!

This is the first time EVER that a dental hygienist has had rave reviews about the state of my teeth.  OK, don't look too closely/my gums are receding and I DO NOT WANT TO DO THAT AGAIN, thank you very much.    

Second bit of success: I carry a rubber tipped gum stimulator in the car and pull it out at stop lights.

Oh so attractive.
