I walked 1/4 mile away from receiver and had 4stucco drywall framed structures and 3 Rockwall fences between transmitter and receiver. It worked great. I intend to use this in the Philippines through a stainless steel gate and a concrete house wall.

Easy install on our office door so we can hear when customers arrive. Loud enough to hear over all of the equipment in the shop.

Straight forward installation. Just pair and install. Nothing complicated.Would definitely recommend.Transmitter connected to receiver (where others fail).

Easy to set up, and worked great at long range through some metal doors and walls that other wireless doorbells we tried could not. Also, receiver can be set to ring very loud, which is nice if you have a noisy work space. Time will tell if the transmitter will hold up to the elements of the weather.

I've successfully installed this door chime inside a package drop box. The box is about 500 feet away and the signal is getting through the steel drop box door, landscape vegetation and a masonry wall. The only gotcha is making sure that both the transmitter and the receiver are mounted vertically. My first install had the transmitter slanted matching the angle of the package drop door flap. The result was some missed signals. This was the third device I tried and the first one that seems to work reliably.Update: The unit sometimes fails to trigger. It works when I test it after a failure. It has failed 3 times in the last 4 months out of maybe 30 deliveries. minus 1 star for being a little unreliable.

Super easy to install, I was able to use our existing magnets on our doors for our Fireworks Business. Customers can now ring the bell to enter from 2 doors or if the door is open for business our Pyros are notified a customer has entered and know to go help from in the back warehouse which makes us much more productive.

What a pleasant surprise. I installed this for a elderly, hard of hearing person. I installed the "chime" in the front hall and it resounded through the house and for a person of normal hearing it would be sufficient. My client also spends a significant amount of time in her TV room and as you can imagine the TV volume is Loud. I purchased and installed an additional chime for that room which really did a good job. The chime has 12 chimes (sounds to choose from) and 4 volume options. The chime receiver can be used to activate all manner of things (relay and voltage outputs). The button itself is somewhat large but it claims to penetrate most building materials. I haven't used it for that. Overall, the product worked well, the instructions were clearly stated. If I had the need I would certainly purchase it again.

This worked so great I bought another. These are commercial-grade units and the distance is GREAT.
