This floss works perfect for me to be able to get under a bridge and does not break on one of my teeth that has a sharp edge. It’s not cheap, but I think you get what you pay for!

Best floss of any type I have ever used!

My daughter is a dentist. She gave me a package of this floss to try- after I ran out I ordered more.

Love this floss. It is very strong and rough enough to get all of the food stuck in between my teeth out. I like that it is black so that I can see how well it works. Now that I've gotten down to the very last bit in the box, I've found a bit of a drawback. The small roll pulls out of the box and I have to unwind it on my own. I can still use the cutting edge to get the amount off the roll that I need and then push it back in the box. Not a huge problem because I love the floss. Also like that there isn't a plastic spool that the floss winds around. It is just magically rolled in a cylinder shape all the way to the very end.

Works as well or better than regular petroleum-based floss.
