Reliable Smoke Alarms with Long Battery Life
Easy to install and reassuring to have a 10-year battery. Clear LED indicator and useful silence button. Good value as a two-pack and meets safety standards.

The smoke alarm and the man from Mogadishu
I arrived in Mogadishu, a good place for any man to visit, despite the nay sayers. “Water on the rocks please barmen.” Having real stones in your water was a definitely a new version of cultural enrichment. Calling me a fat boy as he dropped in the stones. I didn’t understand as I thought I was slim and of a muscular build. Maybe he forgot his glasses that day. Im looking for a Mogi, I said. “Oh the smoke alarm salesman that fit for your home with a 10 year battery life”. He said. “Oh yeah that person” I replied “do you have one?” Not I can’t afford one, but you’re western man who can afford Rocks in your water, it should be fine for you to have such a strong, sturdy smoke alarm that’s a really good product. I want one as it would really give me a a peace of mind in my kitchen and keep my family that much more safer. And it’s only small as well so it wouldn’t ruin the look of hutt. Apprantly the display quality is good and they have a long lifespan”. Just as he finished his sentence Mogi walked it and gave me a package. £15 please. I gave him the money and he instantly walked off. I flew back to London that night happy with my purchase and a peace of mind in my kitchen.

It works, but for how long.
It was easy to fit and works OK but will be interesting to see how long it lasts as the Fire Angel ones I've had previously have never lasted anything like the full 10 years.

Prima rookmelder, tenminste een fatsoenlijk formaat van 12 cm ter vervanging van onze 16 jaar 🫣 oude First Alert rookmelder in de hal bij de keuken. Degelijk en makkelijk te monteren, erg hard en met duidelijke felle led. Hopen dat deze de 10 jaar haalt met de ingebouwde Lithium batterij.
