Not so good.
The white ones were nice & thick but lasted for only 2-3 teeth before breaking. Gave them 1 star.  The blue ones were very strong & made it through my entire mouth. However, could be a tinch thicker as they tended to dig into gums.. I give them 3 stars. Sorry, but I  really miss my Reach flossers. I will continue to use the blue ones for now. If I  only used a few white ones, am I  able to return them?
