The Jet-Setter by Sarah Potempa, $99; joyus.com.The Claim: From inventive stylist Sarah Potempa, who last year sent strands spinning in her rotating Beachwaver curling iron, comes a portable (and totes adorable) mini rechargeable iron. Heating up to 450 degrees and staying toasty for 30 minutes, it allows you to style any time, any place, even if there's no outlet nearby. Expert Opinion:The 7½-inch-long tool is ideal for small jobs, like "taming frizzy bangs or curling your ends," says N.Y.C. stylist Kattia Solano. But if you want to even out an entire head of long, thick hair, you'll probably need an iron with larger plates that will sizzle for more than half an hour, she says. Our Take: "It's great in a pinch," says one tester who flat-ironed swelling strands around her hairline on a humid beach in Barbados. It's also awesome for "smoothing the top layer of hair the day after a blowout."
