Love the simplicity of this door chime. Gives the perfect eclectic touch while softly alerting that the door is being opened. Can work on any door with magnet and adhesive back.
This doorbell is solid and has superb quality. The sound and its volume are also tunable and easy to customize. The ringtones are pretty cool.
Works perfectly in my warehouse which has multiple entrances. Transmitter placed on front door. I have one in my living room and backroom.
Works well, very loud chime. Volume control and chime choice * are a bit clunky but they work.
It seems like you are supposed to open the back with a small screwdriver or tool with the bot notch on the bottom. The plastic just erodes when touched. The device manual itself says 3. Poorly insulated against the weather.
There are zero instructions on how to mount the bell.
