You thought the Zano nano drone was small? Think again.

Unbox Therapy has posted a video showing off what could be the world’s smallest drone, the Seresroad Cheerson CX-10 mini quadcopter, which weighs in at just 0.42 oz and is 1.57 x 1.57 x 0.67 inch.

For comparison’s sake, the Zano Nano Drones weighs in at a hefty 1.94 oz.

The CX-10’s light framework helps ensure a flight time of 4-8 minutes, and it’s powered by a rechargeable 3.7V 100mAh lithium battery.

The CX-10 features a 6-axis design with an adjustable gyroscope adjustable, and it comes with 3 adjustable speed levels.

And if you want to fly the CX-10 at night, it features a flashing LED light.

Check out the Unbox Therapy video below, which also points out you probably shouldn’t fly the CX-10 outside as the wind will certainly blow it away. And the drone is prepared for that, as it comes with 4 extra propellers.

When computers and cellphones got smarter, I think we can all agree that was a good thing. But for drones? Not sure that’s the best approach
