Shreds and breaks for me, unfortunately.
I hate to give this product 1 star just because it doesn't work for me. It shredded and broke a few times during first use. A piece even remained between my teeth. Had to floss some more to get it out. I guess my teeth are too close together to work well for me. I wish the extra roll of floss was wrapped in paper instead of plastic. Buy if you have lovely spaces between your teeth but then you probably don't need to floss.
