Good quality at good price
Easy to install as batteries come with them. Needed drill to install but done easily.
Rabia, 35 - 44, London
Small and good value.
These were really simple to install and now that they have been tested, I can rest assured that they are quietly working away in the background to keep my home secure. The test alarm is really loud, by the way, so apart from performing a test every so often, I hope that I never have to hear them again!

Hello Amy,
After checking with the supplier, I can confirm these Kidde 3 Year Smoke Alarm (Twin Pack) are only recommended to be used with the screws that come in with the packaging, as we haven't tested the alarms on these strips. You could risk the alarm falling onto someone and damaging the alarm.
Thank you for using Q&A

The 3 year phrase refers to a 3 year guarantee not the life of the alarm.
