I bought this knook set because I liked how complete it was and you can't buy knooks of different sizes in stores where I live. I think they work OK, they feel kind of cheap in my hand and the smaller sizes feel like they are going to snap in half as I use them and are very bendy. The cords start to fray at the ends and they were getting caught on my work when I pulled it through. I'm not sure what I think of the knook. I am an experienced crocheter and beginning knitter and was wanting to learn something new, but so far I have found it to be a little frustrating and prefer traditional crochet and to knit with knitting needles.
