When they don't break, they are terrific!
I love the feeling of my teeth and gums after using my Slate Flosser. The problem for me is that the heads often break after just a few uses, and sometimes on the first try. It's becoming an expensive habit!

Better than a water flosser
A ADHD someone who needs to floss, but hates it this is a life saver! I have flossed every single day since getting it. I usually floss every once in a while (like 1-2x a month if we’re lucky) when I need to but this nifty little flosser has me reaching for it daily! Highly recommend. Might even upgrade to the electric flosser next.

Not strong enough
I love the style of the floss heads (the 2 little rubber pieces to massage the gums) but the description says to change weekly. I can’t get the floss past 2 days without the string breaking, making the heads very costly for me.
