I don't think I'd be buying any of these new KitKat Crunchies, not when there's far better chocolate out there. But who am I to tell several millions of people that they're no good, you guys love them and that's all that counts!
Of course Mint Aeros aren't the best chocolate you've ever tasted - probably nothing from Nestle would be. But they've got a market and they do a good job of supplying people with sweet confectionary.
