21 hits and misses from CES

The human-carrying drone from Chinese manufacturer Ehang generated the biggest buzz at CES this year, says CNN correspondent Samuel Burke (pictured).

The tiny, autonomous helicopter is just 18 feet long and can be folded into a five-foot space.

The prototype is called "184," seats one person, and takes off and lands almost vertically. The 184 can travel up to 11,480 feet high, go as fast as 62 miles per hour, and fly for up to 23 minutes on a full battery.
