The 2nd Gen Blink Video Doorbell is a polished product which performs well for the most part, but has some obvious shortcomings.

SwitchBot makes a range of interesting, and usually pretty good smart devices. Their first doorbell is not one of them, under-performing across the board.

The TMEZON Bell 24T Smart Home Doorbell demonstrates surprisingly good image clarity for its price range, but there’s very little else to praise.
