Query: Didn't work for me!

As my title for this review states, IT DIDN'T WORK FOR ME! I am desperately trying to stop biting my finger nails, and this was the first product I tried. The product description (and statements from other people who liked this product) states that it works wonders and will turn you cold turkey in no time. It does not have a nasty taste or smell at all, and it comes off your nails easily after a days use. I tried a different product, "Mavala Stop," and it is marvelous, for it does everything that this product doesn't. Mavala Stop is worth the extra three dollars you'll spent purchasing it, unlike the Bite Ender, which I want my six dollars back for.
