I bought a twin-pack of the FireAngel ST-620 smoke alarms in August 2018. I had to replace the base from my ancient and larger alarm with the smaller FireAngel one, but I was able to reuse the existing screw holes, so an easy job. I have never had any false alarms, unlike my old units which went off with a 'smoke' from the kitchen, and the a new units are modern and stylish.

However, like others, one of the units started intermittent chriping in February 2021 - a low battery warning despite the alarm never going off. I read lots of reviews from people with the same problem, and discovered that other brands using a 10 year non-replaceable battery suffered from the same issue. I also read of people having difficulty getting replacements or even a response from Fire Angel, so I was somewhat concerned.

I sent an email to FireAngel giving details of the problem, the batch number and advised that I had the original receipt, but I didn't send it or even a photo or scanned image. I got a response within 2 days advising me that they had posted a replacement, which arrived within another 3 days. In my case, the response from Fire Angel was excellent although I'm concerned that the second unit from my twin-pack will suffer the same fate in the not to distant future.

Can’t replace the battery so have to renew the whole unit. Sustainability? Lasted 2 years not 10 as ‘guaranteed’

One has packed up after two months. Keeps on going into full alarm.
Took the issue up with Fire Angle as it has a warrant, they where not interested at all.
Buy a better brand as these are pound shop junk
