Smoke Alarms for Home 2 Pack, Isafenest Smoke Detectors with 10 Years Sensor/5 Years Battery Fire Alarm with LED Indicator, Photoelectric Smoke Alarm Battery Operated, (LZ-1906)

Fire alarms. Would recommend I have not tested them in a real fire and hope I never have to. They have a flashing red light, that indicates they are functioning and pressing the test button sets them off. Installation was simple and easy to do. Reliability is unknown as they have only been installed a short time.. I would recommend them simply as not having one is too scary an option. And at the price these are, they are worth every penny.

quality product, easy to fit and great value for money

Very easy to install and well built, although it is quite smaller than expected. But it does the job sound alarm is loud, and accurate very alerted. Not sure about battery life yet but definitely good value for money I will recommend

These are good value for money ,easy to install and are working well.

seem like good quality and a nice compact size tested ok no live test so far thankfully

Easy to install

I bought the Isafenest Smoke Alarms 2-Pack for my dad to replace some of his older smoke detectors, and I’m really happy with the purchase. These alarms are compact and discreet, so they don’t stand out too much on the ceiling, but they still do the critical job of keeping the home safe. The 10-year sensor and 5-year battery life give real peace of mind, meaning we won’t have to constantly worry about maintenance or replacements. I also like the LED indicator and the easy-to-use silence button — both features add extra convenience. Overall, a great product that’s essential for any home. Highly recommend!

If you want linked-up alarms that work, then this is a good brand. Works very well, can hear it outside when it's tested every month.
