As arthritis is setting in I thought I'd give this ergonomic style hook a try but I am really glad I only bought a single hook and not a set. First con, the price - muy expensiva to say it nicely. Second, the hook is pretty heavy compared to a regular Susan Bates aluminum hook. Third unless you hold your crochet hook like a toothbrush you won't like this hook, if fact it is shaped exactly like an Oral B toothbrush handle.
I love how the Addi Swing conforms to my hand. It makes for painless crocheting for me. Traditional hooks tend to give me hand cramps. Whether this hook helps you may depend on how you hold your hook or your hand size. In any case, I would suggest trying this if other hooks make your crochet hand hurt.
