Good product, easy to connect up. Found it hard to find information regarding this on the net. This will work with any ERA system. Connected seamlessly to my G5 alarm. Great advice from Safe when I asked a question, will buy more.

Good addition to our ERA alarm system for an unprotected door. It's easy to install, easy to setup and it works seamlessly.

If you're looking for a modern alarm, these ERA alarm systems are recommended and I would definitely buy again from safe.

Very good value for money and easy to install and set up with the app.

I bought this additional door sensor when I moved house. It was easy to set up, straight out of the box and works properly that I feel safer at home and safer that my home contents are better protected whilst I’m out. I’m disabled so cannot manage wiring and being up ladders. This is a good wireless sensor that extended my existing ERA board and accessories. The only problem I had was with my internet provider sorting out my connection issue with their server. But that got sorted with a phone call and some resetting. Would recommend - security seems necessary

Look smart and blend in well with door

Easy to set up and easy to use

Easy to find out if working by going on test and the lights light up on the sensor to

One stuck in the correct place never had a problem in summer or winter they permanently stayed in the same position doing a fantastic and great job

I would recommend anyone who wants an alarm system to use these on doors and windows as they are easy to use look good and work to a good standard

I will be putting some more shortly to add on to my original set up

Great item, bought as a add on to existing alarm system. So easy to do its child's play really. Like the system immensely and it gives piece of mind. As always a really easy process and no fuss to purchase.

Excellent service.

The sticky backing on one of the sensors did not stick well on the door frame and had to be stuck with glue. The sensors work very well like its supposed to.

Spot on, connected to existing system perfectly.

Excellent add on to system
