Cleans well and is easy to handle with a little practice. At the price cheaper than in the shops. The 4 rich certainly 1 year at me so also very economical. I can only recommend. But always make sure to buy unwaxed, because this has by her aufspleisen the long run on Zahnf a better cleaning effect. Waxed is no better or worse between the teeth is only slightly easier in the first experiments with dental floss.
