Walkie talkies unlocked hours of independent play — and no Wi-Fi required

Walkie talkies unlocked hours of independent play in my house — the kids disappear into the backyard and I can actually hear them from the kitchen without standing at the window. No Wi-Fi, no screen, no batteries to replace every two hours because these take AAs and last forever. The retro design is a bonus; the real magic is that they just work, which is more than I can say for most kid gadgets.
