The best smoke detector
⭐️⭐️⭐️⭐️⭐️ Excellent Smoke and Carbon Monoxide Detector Set!I’m really impressed with this 3-pack of photoelectric smoke and carbon monoxide detectors! The installation was super easy — no wiring needed, just attach them where you want, and they’re ready to go. The design is sleek and modern, blending nicely with my home decor.What I love most is the sealed 10-year lithium battery, so I don’t have to worry about changing batteries or dealing with annoying low-battery chirps. The alarm is loud and clear, giving me peace of mind that it will alert my family in case of danger.Overall, this is a reliable, high-quality set at a great value. Perfect for adding extra safety to your home without any hassle. Highly recommended!

Reliable and worth it
I like this smoke detector because it’s lightweight and easy to pack, but still feels sturdy and well-made. The photoelectric sensor reacts quickly without being overly sensitive, and the silence button is a lifesaver when I’m cooking and don’t want to set off a full alarm. Setup took less than a minute; just pop in the battery and it’s ready to go. Whether you’re using it at home or taking it on trips, this is a smart buy for anyone who likes feeling safe and prepared.

Smoke detectors
This compact, battery-operated smoke detector features a photoelectric sensor for reliable detection of smouldering fires and a convenient silence/hush button to mute non-emergency alarms. It’s easy to install, portable enough for travel or temporary lodging, and provides good peace of mind without complex wiring.

Will not be buying these again
These are not UL tested if that’s a requirement in your city/state. Half of them will not go through test cycle when the button is held so they fail inspection. I have had three develop a ‘crackling” electronic noise and had to replace with other brands. I’ve installed 14 of these in the last year and will likely need to replace them all out of concern for reliability in my rentals.

Great!
This fire alarm works great and gives me real peace of mind! It comes with a built-in 10-year battery and includes all the hardware needed for installation. The setup was super simple thanks to the easy-to-follow instructions. I love the sleek, modern design it fits perfectly where I needed it.The alarm is made from high-quality, durable materials, and the test button is a great feature for checking functionality. It’s been very effective at detecting smoke quickly. During a recent cooking mishap, it went off in time to alert me before things got out of hand. The high-pitched sound is loud enough to wake me up at night, which adds to the sense of safety.For the price, this smoke detector is a fantastic value. It’s reliable, easy to install, and definitely worth every penny. Highly recommended!

Good Smoke/Carbon Monoxide Alarms
These alarms are easy to install. The battery lasts 10 years when it goes dead you should replace them which is a good reminder as any smoke alarm should be replaced after 10 years. The one thing that did not seem to be clear in the instructions is when activated (screwed in to the base) it will flash green twice, alarm twice and then alarm for 15 times. The unit is not defective it is it’s test cycle.
