Expensively Useless
The Hummingbird product is, basically, a cell phone vibration mechanism with a plastic toothpick attached.  These replacement attachments do not hold any value for a person that has a serious investment in their teeth.  A regular toothpick provides more rigid action while being less cumbersome.<br /><br />I promise you that the free toothpicks at any place you eat will beat this gimmicky Hummingbird product, hands down.
