Floss breaks way too easy.
As a lifelong flosser I was excited to try this floss.  I like the feel of it, its thin and seems to dig in to any buildup on my teeth.  Thats where the good review ends.  The box and metal cutter are pretty flimsy and I am always in danger of loosing the end of the floss back into the box.  The biggest concern I have is the weakness of the thread.  My first floss lasted a few seconds and the floss broke.  A second peace broke in the same spot. After four breaks I pulled out a different brand and flossed that tooth with no breakage.  I tried going back to my original floss and broke it twice before a successful round could be completed.  One break or two I can understand but this was too much.  The slightest sharp edge on a tooth renders this worthless.
