tiiwee X3 Wireless Home Alarm System, White - Loud 120dB Siren, 4 Door & Window Sensors, Battery Powered, Touch Control, Photoelectric

A very simple and effective piece of kit. Installed on new uPVC doors, angled the sensor on the profile of the frame, magnet on the door. All the sensors are already paired with the base unit. Very loud, loud enough to wake the wife from a deep slumber on a Sunday morning when I forgot to disable it and opened one of the doors! Probably woke the neighbours too come to think of it. Can't comment on battery life yet, and the sensors use tiny batteries (A23 / MN21, https://www.amazon.co.uk/s?k=a23+battery), so might have to stock up on those in advance.Overall, great value for money.

For the size its loud as anything and price you couldn't beat it. The set ul was super easy and not my house, garage and shed are all geared up.

Great Security Sound Setup, Quick & Easy.

So far so good

Great simple system easy to install and effective.

Very low level sound when set off

Would certainly recommend this alarm. Spent quite some researching different brands and options for home security. Finally settled on a simple alarm system. Easy to install and use and not an eye sore on doors or windows. Very loud and worth the money

Good little system very loud too.
