I felt like something had been taken off me from under my feet because there was not supposed to be something plugged into my internet, I was led to believe it finds its own internet. However I was vulnerable at that time as I had just been burgled. Subsequently the alarm would go off without any intrusion. I reported this and on two separate occasions it was attended to but on the third occasion it wasn’t and later I was told to read my manual which was emailed to me. But it continued going off without intrusion so I turned it off until I went away when people I had left to attend to the intruder alarm eventually complained that it was going off without intruders. I then left a one star rating which was responded to very promptly and I am Very Pleased that I can now set my alarm on and go to sleep without being woken up unnecessarily.
