It is very useful and easy to set-up. It also very affordable in terms of the technology it is providing.

Terrible purchase, I was able to connect the alarm to my security system, but after a few days the siren would go offline. I reset and reconnected the alarm more than 10 times, in the end my Wi-Fi network could not even see the device, I even tried different adaptors to no avail. I will be returning the product for a refund.

I bought this (along with the Connect PIR sensor which you need) for our garage, the bonus is you dont need a smart hub to control them which means they are pretty cheap. The PIR sensor is good, but the reaction times for the sensor and the alarm are a bit slow, ie I am in the lounge room by the time it alerts me that I was in the garage. It's also not very loud, which is fine if you are home but unless you live super close to your neighbours they are unlikely to hear it and it's not really loud enough to be that annoying to thieves. It is very consistent and does function like it should which is a plus. And obviously the ability to turn it on and off remotely is great. It's not super easy to set the alarm 'automations' but its not impossible either.
