Good value. Works pretty well. Can be a bit glitchy sometimes. We have high speed WiFi but despite that the ringer only works 90% of the time, phone alerts are slow/delayed, and so far the “call” feature has only worked a couple times and then stopped. The app is lacking a few features that would be nice to have (PIR triggers ringer, doorbell quiet schedule, alert includes photo). The ringer sound options are terrible (mostly tacky music, lacking in modern alert type sounds). Other than these things, the doorbell is good quality, looks great and works well most of the time.
Item works perfectly, pairing with Swift Smart app without issue. Camera works well. Works with micro USB 5v or battery.
