[This review was collected as part of a promotion.] This is a very nice video doorbell and that's coming from an existing Ring doorbell user! The setup was a breeze, slightly easier than my other one. I appreciate that it's not battery-only, but actually offers hardwiring as an option without needing a completely different model. Mounting is secure while maintaining ease of removal to charge with a standard USB-C cable. The video is clear in color or night vision and connection to the app is quicker than my other one was when it was new. Highly recommend!
