Feel free to throw out your other curling irons, ladies, because there's no way any of them can compete with the Sarah Potempa Beachwaver ($199, Sarahpotempa.com). With this genius tool, all you do is separate a small section of hair, clamp the end, and press a button. The rotating iron does the rest. It works to spiral hair over the entire length of the barrel, so when you release you're left with the perfect beach wave.
