I've had this set nearly two years and find it invaluable. It makes tracking rows very easy, and the set means I have the proper size for whatever project I'm knitting. I knit with a lot of fuzzy, specialty yarns which could catch on any sharp edges, but these counters are so well-made that they don't cause a problem. I design many of my projects. I just use the row counter and then add a stitch marker every ten rows to keep track. Then I can write down the pattern at the end. Thanks for making such a quality product. I tell all my knitting friends about these row counters.
