High-tech gimmicks are rife when it comes to appliances these days, but the one distinguishing LG’s LFXS30796D refrigerator – a peek-a-boo window that helps conserve energy – is a little more useful than the ability to stream YouTube videos. Clad in black stainless steel, the 36-inch French-door unit features a tinted glass panel that lights up for 10 seconds when knocked on twice, letting users scan the contents inside without having to open the door. A door-in-door feature holds oft-used items within easy reach, and a slim, built-in ice maker frees up storage space.
