## Customer Reviews

### ⭐⭐⭐⭐⭐ Great for toddlers bedroom door.
*by A***R on 4 July 2025*

I got this for my toddlers bedroom door so I would get woken up in the night if he started wandering. It's really easy to install, lots of settings. Loud enough to wake me up when his door is opened as I wanted it to, and a large variety of tunes but to be honest the basic one is enough. Good quality.

### ⭐⭐⭐⭐⭐ Met expectations regarding quality, ease of installation, and really effective usage
*by A***P on 21 March 2024*

Versatile, neat, with a good, very loud for it's size, urgent alarm, with lasting 1 minute option if not stopped before using handy portable remote or slider on/off alarm housing switch. A good, well priced product, and very efficient standard Amazon delivery.Designed for flush fitting doors to frame. I found it needed packing underneath the magnet, and more if it was a recessed door or, say, a window frame with sloping mitres on the slope, but easily rectified.

### ⭐⭐⭐⭐ Works perfectly…….
*by M***R on 13 April 2024*

The unit is really easy to set up and fit to your chosen location.You are able to fix it to the surface with self adhesive stickers or fixing screws supplied.Once a door is opened and the connection separated,the alarm is activated.Works really well and gives you added security.The main receiver plugs in to a socket in your chosen room.
