Addi Click Crochet Hook Accessory Set

I have this set. I have never used them attached to my click cords, though I purchased them thinking that was how I would use them (haven’t tried my hand at any Tunisian knit yet), but do consistently reach for them when my project is on the coresponding diameter needles for picking up stitches, crocheted cast ons and some bind offs. Note that I made sure to test each of the connections upon purchase, as I’ve had at least one addi click item (one of the heart stoppers) come missing it’s spring, though never so far in any of my needle sets (lace, long lace, bamboo, and the currently on offer crochet).
