Very good.

I use these at least 3x's a day, after each meal. They remove all of the stuck food easily and my dentist has told me to keep doing what I'm doing because my teeth and gums look great.

No more excuses to not floss

I am often guilty of skipping my flossing routine. Using the strings is tedious as both hands are required and expert maneuvering needed. This gives me no excuse as I can use it single handedly. I put them everywhere, including my car, in front of my computer, at my work desk, even in the gym bag. It is small but flosses well, the string is sturdy and does not break through the entire teeth flossing session. I was actually given a pat on my back at my latest dentist appointment for noticeable improvements in my gum health from regular flossing.

Work well but sometimes break

I really love using floss sticks. I find them convenient and it leaves me no excuse to not floss my teeth everyday. The only downfall is that the floss strand sometimes snaps, making you have to use another one to finish the job.
