In almost all cases I never trust infomercials, partially since they always over-sensationalize common "difficulties" with everyday products (oh sure, I often slap frantically at a pile of Tupperware because I can't ever find the right lid). One day, however, I saw an infomercial for a thingy that was supposed to open clamshell packages easily by breaking the seam. For once, the person on camera struggling mightily to open that package was actually a good representation of real life.
I'm all for more companies going to this. I can sort of see why clamshell packaging was found to be useful in retail stores (definitely prevents opening the package and slipping the product into a pocket), but it's absolutely useless if you're getting the product through the mail. Now if only Monster would stop gouging their customers' wallets as well as their fingers...
