Best Selling IoT Product ... RING
2017-06-26
I believe the RING is the best selling IoT product. It replaces standard doorbell with Camera, Microphone and Speaker. When someone passes by or press the ring, it apart your smartphone and let you communicate. It is a great idea and for less than $150 ... you have a peace of mind.
This would ends "Doorbell and Run" prank ... It is called ピンポンダッシュ (Pingpong Dash) in Japanese.
