Pricey but worth it in my opinion
5/5
These things are expensive when you compare them to a regular wired alarm, but they are good, and what price do you put on safety.
Some of the features might seem a little gimmicky on first glance, but with young kids they are actually quite useful.
Night lights to show the exits for instance, and voiced warnings before an alarm telling you of where the problem is, rather than all alarms going off and giving you no idea why or what’s happened.
Also, with most other systems you can’t mix battery and wired alarms, so unless you get every location spot on when first installing cables, you can’t add any additional rooms at a later date, but with these all you need is either mains power, or batteries as they don’t require a signal cable between every alarm like others.
They also perform their own periodic test so if you struggle to remember to do this yourself, you get a little chirp every now and then to tell you and a report in an app. Happy days.
