I tried one of them out this morning. I like the feel of holding this device as I'm crocheting. What I do not like is the fact that it repeatedly folded back in on itself as I crocheted. I think I expected it to be like pocket knives that are a bit stiff to operate and this is very loose. At the present time, these items are only available at select Walmarts (per a post on Boye Facebook page). The cost for one of these is almost $8.
