How we test
Overall score is based on smouldering and flaming fire sensitivity.
“Good” or “OK” meant the alarm sounded quickly enough to alert you to danger.
“Poor” meant the alarm took significantly longer to sound.
“Extreme” sensitivity meant the alarm sounded so quickly they are more likely to issue false alarms.
Ease of use includes instructions and ease of installation.
Noise is measured in a quiet room 3m from the alarm.

Not good value
Pros
It is very loud.
Cons
I had FireAngel smoke alarms installed in my house 5 years ago. They have all stopped working within the last year. So the 10 year lifetime is misleading. They don't have batteries you can replace so once they stop working you have to remove them. But there's a warning on the alarms that you can't dispose of them in the rubbish so you need to find a special hazardous waste disposal. I will not buy this brand again.
