Review: Best system by far - Works great synchronised with full kit and external siren and surprisingly easy to set up, had 3 different types of this sort of kit but definitely the best so far and looks like a very expensive system when installed. Great product thanks
Review: Small, looks nice and does the job - I purchased alongside the "JC Wireless GSM & WIFI Security Alarm System, Home and Business RFID Burglar Security, Support Auto Dial, Multi-language GUI and English APP Control , with Pet-friendly PIR Detector, Door Window Sensor,Remote Controller, RFID Tag, and Warning Sticker". It is a great piece of kit but I ordered it thinking it would work with the above alarm system as it did not come with a siren, and I assumed the siren could be mounted outside. It is for indoor use, don't get the reason for it being inside but never mind. So not negative about the product, just my miss-understanding. It can be used as a standalone system, might be good for a flat, shed, garage or something like it. It looks modern, I used the door sensors and sensor with the above alarm system and it all worked well, was simple to pair. Great customer service.

### ⭐⭐ Was good for 1 year :(
*by J***. on 5 April 2020*

Alarm was great for 1 year. Worked as should, not the loudest but enough for the garage i used it on. Now the round sounder unit functions but has gone very quiet and crackles. Shame it hasnt lasted long, would have hoped to get at least a few years from it.
