So, this toy was delivered to my job today about 2pm.  By 210pm, I had one side of a link removed and a bent pin.  I was so pissed because I thought this was the only pin in the pack, but found a plastic bag with 4 more remaining of varying sizes.  Be very careful, because this tool is flimsy and plastic like a toy, and the pins are very delicate.  As another reviewer mentioned, take care to line the pins up carefully or else you'll be replacing this tool after removing two links, as the pins break easily.
