"I can't believe how easy this was to setup. Out the box and in less than 5 minutes it's ready. Tested with all the windows and doors in my 2 bedroom flat and it's activated on the opening of them all. Key Fob range is fine for disarming from outside. Would definitely recommend. Clever technology!!"
"I presume this is a volumetric and/or perimetric type of alarm, similar to that used commonly in vehicles. The alarm was ok until the wind started to blow outside, when presumably the air pressure inside the house changed. The alarm then went off by itself and on numerous occasions when we returned home the alarm was still operating. . There is no timer on the system to prevent this. Sometimes it just didn't work at all when an outside door or window was opened from the outside. Also there is no outside alarm siren/bell capability, so neighbours cannot here the internal alarm. Further, one sometimes needed to be just 2 metres from the control unit to switch it off remotely. I have scrapped this unit - not fit for purpose at over a hundred pounds sterling and certainly not worth the money - and have bought the reliable Yale premium wireless system - brilliant."
