It works consistently and flawlessly, its app is great. It consumes about 2-3 watts per hour at 5 volts. The image is decent for 720p despite claiming to be 1080p (obviously upscaled).
Don't expect good night vision beyond 2 meters or in complete darkness.
The negative aspect is its limited wifi range, as it loses signal with a distance of 5 meters from the router and one wall in between.

A bad product, bad camera, bad wifi connection, good operating platform from the play Store. Overall, it disappoints as a camera. I do not recommend it. Poor value for money.
