Optical Smoke Alarm Kupu 10 for Home - with 10 Year Lithium Battery - Scandinavian Design - White

Good quality

Looks stylish, not like the plastic cheap looking ones. No visible buttons.Works very well, not too sensitive but goes off when there is a small amount of smoke. Very loud, Easy to reset.I will be buying another one once it needs replaced

Very neat wanted it to go on a black ceiling looks good , only thing they are a bit expensive but I am going to order another for downstairs.

Looks great. hopefully will work if needed.

As everyone else has said, it's a bit tricky to set up. I was trying to twist the outside edge of the back plate but you actually need to push down and twist the middle section. Use the palm of your hand with a rubber glove on haha!! It clicks a few times and you're ready to put up. It's stuck well so far.... Can't show you a photo as it's grey on a grey wall so completely camouflaged!!! Exactly the point!! No more ugly white plastic alarms. Not sure how I'm supposed to remember when it's 10 year life is up???? I'm hoping it starts beeping or something!?!?

Bought this for my bedroom as I wanted a smoke alarm that looks good and doesn't have a LED on all the time.There is an LED under the fabric that comes on but very rarely.Easy to install, either screw to ceiling or use the supplied sticky back pad.Smaller than I imagined. Discreet and good looking even when noticed. Way better looking than your average smoke alarm.

Really cool stylish looking just a pity they only do these as a battery operated solution and not able to connect to mains power.

I purchased and installed three of these less than a year ago on a ground and first floor. Within three months, one sounded randomly in the middle of a cold (around 0 degrees) night on the second floor. I assumed it was due to condensation and gave it a second chance. It woke us again a few weeks later on a warmer night so I replaced it with another. The other was set off in the middle of a moderate summer night, so I assumed it was faulty and removed it. Shortly after the downstairs alarm also sounded randomly in the middle of an otherwise pleasant and smokeless summer night. Their appearance is delightfully discrete and their alarms suitably alarming, but their alarm being set off appears to bear no relation to fire or smoke in my experience.
