This colorful watch keeps track of your kid's whereabouts

You should even be able to set a geofence -- an imaginary boundary on the map -- and get alerts sent to your smartphone if they leave that area. And because the watch has a cellular radio inside, plus a microphone and speaker, your kid can call for help too. Press a single button on the watch, and it should immediately phone home or dial one of five phone numbers that you can pre-approve.

I say "should," because we didn't actually get to try a working CareTime at Alcatel's product-filled hotel suite at the 2016 Consumer Electronics Show, only a mockup. (Admittedly, it was a mockup with a comfy silicone rubber band and an Apple Watch-style reverse clasp.) But I'm not too worried about it being a dud. The CareTime is just the latest in a new wave of colorful, inexpensive smartwatches with the same basic idea.

A better question: Will you be willing to pay a cellular carrier like AT&T an additional fee every month (typically $10) to add a kid-tracking watch to your plan?

The CareTime will go on sale this April in Europe and Latin America, and should arrive in the US by the end of 2016.
