I love the idea of these little flossers in that hey can make flossing particularly the back molars much easier. Unfortunately these just cannot handle my tight teeth caused by my braces. The floss separates from the plastic almost immediately when trying to use them. If it doesn't separate the floss itself rips into threads leaving fibers between my teeth. If you are going to use this type of floss, I would recommend saving your money and purchasing the life brand from Shoppers.
