Call bell for assistance outside. Paired this set to the other two transmitters and receivers. When pairing, I had to hold Button B for longer than 5 seconds before I got the blue indicator light to blink, so be patient and just try again. The transmitter isn't easy to slide off the mounting clip, but it can be done. Interference from metal garage door and power lines, no signal was transmitted. Improvements: transmitter lanyard clip, less sounds, louder volume.

Using this in a house as a call bell for assistance. Previously purchased one receiver/transmitter & additional transmitter. (One receiver alone, isn't loud enough to be heard throughout the house.) Purchased this additional receiver to have in another room. Successfully paired it to the others, so both transmitters now activate the chime on both receivers.

This is being used inside a house as a call bell for assistance. The transmitter (button) though easy to press, can't be pressed by accident which is a good feature. It can be squeezed in a hand as well as being pressed with a finger. There is a definite click, when it has been pressed down completely. It is able to transmit through doors and walls from one side of the house to the other.

This is being used inside a house as a call bell for assistance. Receiver has three settings for volume, I had to set it on the loudest volume. 83d is only at 3ft (1m) The receiver has holes projecting the sound against the wall, rather than having the holes on the front to project sound out towards the room. 35 chimes, from 5 to 27 seconds long, various volumes & themes: classical, holiday, novelty, animal, doorbell chimes. Paired additional transmitter.
