I'm a loyal FireAngel customer and these smoke alarms maintain the brand's excellent reputation. The quality and reliability are second to none, which is exactly what you want from a safety device. Installation is straightforward and they're up and running quickly. The optical sensor technology works perfectly - sensitive enough to detect real smoke threats but smart enough to ignore false alarms like vaping, which is a huge advantage over cheaper detectors. The alarm tone strikes the perfect balance - loud enough to wake you and alert the household, but not so overwhelming that it's painful. There's no annoying constant beeping during normal operation either. The 10-year battery life is fantastic - set and forget peace of mind. The white finish looks clean and unobtrusive on the ceiling. Pro tip: pair these with magnetic mounting pads (as mentioned in my other reviews) for incredibly easy installation without drilling. These are premium smoke alarms that justify the price with superior performance and reliability. When it comes to fire safety, I wouldn't trust anything else. Highly recommended for anyone serious about home safety.

Works well easy to fit, good quality and value for money.

Compact and modern fire alarm. Easy to use, comes with a mounting base, screws and wall plugs. Mount the base to a wall or ceiling as per the instructions. Then place the alarm in and twist to the base to hold in place and activate the batteries. Easy to test by holding the button, and has an indicator light. Says the batteries should be good for 10 years, then just replace with a new device, so no hassle. Bought this one as FireAngel are a reputable company.

Bought 2x of this item to replace older battery fire alarms on both floors of my house. Swapping them out was very quick and the integrated battery meant I could test them instantly and have peace of mind that they would work and keep everyone safe in ann unfortunate event. As an added bonus the old detectors had started to yellow with age and these new ones are a clean white blennding in with the ceiling much better and looking neater.

The FireAngel Optical Smoke Alarm is exactly what I wanted for peace of mind at home. Installation was quick and straightforward, and the instructions were clear. The alarm itself feels solid and well-built, and I like that it uses optical sensing-it seems very responsive without giving false alarms from cooking or steam. The test function is simple to use, and the loud alarm is reassuringly powerful. Battery life appears solid so far, and it gives a clear low-battery warning, which is very helpful. Overall, it’s a reliable, high-quality smoke alarm that provides confidence without fuss. Highly recommended for home safety.

Good product with a long battery life. Easy to install. A brand you can trust. Very loud when activated. I previously had one for by the same company for 10 years.

Hopefully as this is a non replacement battery it lasts as long as claimed. Slightly different fitting to the older model, but made it fit

Good quality
