I always use unwaxed floss, and am used to dealing with it. This, however, seems to me particularly hard to hold or to knot at the end. By their nature (thin and very smooth) she slips me very easily from the hand. Once knotted the end, however, she does her service and is very convenient. Highly recommended for people with very nimble fingers ... I'm going to pick the next time a different variety, also unwaxed, but grippy.
