I used to use floss picks but found them inconvenient after a while. I have gone back to standard floss. Once I found a brand and style I liked I have no desire to switch back. The flexibility and convenience is well worth it
I use the floss picks too! I hate holding floss and these cut out one of the steps that I have to do, so I am more likely to succeed and get it done.
Floss picks have worked great for me, I have always considered Gargling and swishing the water around your mouth similar to a water floss.
