I bought this against the advice of the Wizard Product Review. It was alright I guess but the risk
of cutting yourself doesn't in the slightest inkling out way the outcome. The gimmick doesn't adapt
to most floss containers and it isn't that great. Neither is it as convincing as the needles as you
can't show your mouth after the blades are put into it. Whatever reactions you might get are more
just because you put razors into your mouth, not so much that they were convinced you swallowed
them. Save your money and get "A single Needle" by WH.
