Easy to install and connect

Great range easy installation

Decided to buy extra sensors to put on all the downstairs windows, easily mountable with the included sticky pads (so no holes drilled in my nice new window frames). Easy to pair with the system and works reliably.

Bought YALE alarm kit - needed extra door/window sensors. Worked perfectly - was up and running within minutes.

love this for peace of mind and safety. We brought it to go with the full Yale alarm system as an extra. Works well and easy to install.

Cheapest from everywhere.Very good deal.

OK and with just about enough range to cover a shed 20 metres away. Easy enough to add to system.

Great door sensor and easy to install

Rather expensive for what you get. However, easy to add to my existing system and the adhesive pads I was worried wouldnt stick were actually very good.
