Safeguard Supply Wireless Doorbell, ERA-UTDCR Door Chime, Ideal Wireless Door Chime for Business & Home, Long Range Wireless Doorbell Goes Through Multiple Walls & Floors, Concrete, Metal & Brick

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 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 love when it goes off, scares my coworkers. We use this for the back door

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.

We put the unit in the mailbox which is a 1/4 mile away and got no signal. We then put it on the outside and it worked. I went back out and it didn't work when my utility vehicle was in front of the mailbox. The mailman will have his SUV in the way when he opens the mailbox and that will block the signal even more. I didn't see any way of getting around that problem after thinking about it and decided to send it back. The idea and product is good, but wouldn't work in our situation. The ad says 4000 feet and goes through metal and more but my smaller vehicle blocked the signal and the mailman's is bigger.

I have tried the 1000' and the 1300' foot range doorbells - even one that claimed to go through "4 walls" and they all did not work. This one did and does every time.

I got this for an elderly relative who lives about 1,300 Feet away to use as an alert, not for emergencies. I wanted a long range, loud doorbell, that would fit in her pocket. But one that would alert me that she needs something, rather than calling 911. She already has one for 911. This works great. Recommend if you need a loud long range doorbell.

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

Habia probado otros aparatos con alcance de 300 m y no llegaban hasta caseta de vigilancia. Este si alcanzo a timbrar desde dentro del elevador hasta la caseta de vigilancia. He querido comprar otro timbre transmisor para que sirva desde otro elevador hacia el mismo timbre receptor, pero no lo he podido localizar
