I got this idea from a magazine. Go to this link: http://www.target.com/gp/detail.html/sr=1-5/qid=1169914582/ref=sr_1_5/601-4486323-2759321?ie=UTF8&asin=B000JZ8A1M. Scroll down and click on "features". Read what it says. Then click on "Description" and read what it says. It's sort of stupid for a smart item. Just a bit of irony.
