## Customer Reviews

### ⭐⭐⭐ 







  
  
    Button not 100%
  

*by P***) on Reviewed in the United Kingdom on 20 September 2019*

Nice door bell with two buttons, however I have noticed people saying the pressed the bell push button and it did not work. On investigation I found the button has to be pressed on the left/top side to work, anywhere else and it does not.I put a small notice at the side of the bell push to inform visitors to press the target area I marked on the button.UPDATEThe vendor kindly posted me a complete replacement however it is still not working correctly but seems random. People just walk away. (Note the bell push in question is only 10yards away from the receiver, and the second bell push is slightly closer so the operating range comes into question.

### ⭐⭐ 







  
  
    Working distance and reliability may not be what you expect
  

*by D***. on Reviewed in the United Kingdom on 13 August 2019*

I needed a bell at the gate as not all delivery people like entering if the dogs are in the garden and this seemed to be the perfect solution. However, I found that the push buttons are unreliable, sometimes they work, sometimes they don't. Not everyone is going to realise that the light should come on when you push it and press it again if it doesn't. The gate is only about 30 feet away but put a gate post and a stone wall in the way and it just doesn't work reliably. Disappointing.

### ⭐⭐⭐⭐⭐ 







  
  
    Super choice
  

*by R***I on Reviewed in the United Kingdom on 7 September 2019*

I am not a technophile so was really pleased with how easy these were to install. Everything you need is enclosed and it is very easy to set up two different ringtones. Delivery was on time also.
