[This review was collected as part of a promotion.] I received a free product in exchange for my honest review. All opinions are my own. This is a great combined smoke detector and carbon monoxide detector by First Response. It hopefully last for years like it claimed to. So far the battery and unit are working great. I definitely recommend.

[This review was collected as part of a promotion.] Great alarm that detects both smoke and CO! Game changer to have this all in one. Easy to install and use. Do I think the battery will last 10 years? I guess we will see.

[This review was collected as part of a promotion.] Safety first! Great device with a very loud alarm. This is a reputable company with great smoke detection. Simple design. Long battery life. Buy more than one!

[This review was collected as part of a promotion.] Easy to use and does the job well! The sound is loud enough for everyone to hear it if there is ever an emergency. If it happens to go off for something like burnt food, it is very easy to silence so you won’t have to worry about that.

[This review was collected as part of a promotion.] This is a very convenient option for an apartment or being able to place in an area that you don’t already have a fire alarm and carbon monoxide detection It is super easy to install and the ability to place it where you need. It makes it super convenient. The fire alarm was very simple to install. It has a ten year battery and didn’t need to be hard wired. Simply used the supplied screws to attach the base to the ceiling, pulled the battery strip to activate, and twist the unit onto the base. Easy and quick. Will still work if our home’s power shuts off. Replace in ten years.

[This review was collected as part of a promotion.] This was really simple to set up and install. The instructions were clear and I was able to have it up and running in just a few minutes. Shortly after I burned something in the kitchen and was able to see that it works just fine. That said, it's been up for weeks and there have been no false alarms.

[This review was collected as part of a promotion.] Getting this smoke alarm with CO detection make me feel safe, the design is very sleek, installation was easy to apply. Definitely a must have in a home.

[This review was collected as part of a promotion.] I couldn’t be more impressed with the Smoke and CO Smoke Alarm! This device is a must-have for every home. The combination of smoke and carbon monoxide detection in one unit ensures double the protection without needing multiple devices. Installation was incredibly straightforward, even for someone who’s not tech-savvy. The alarm is loud and clear, making it easy to hear throughout the house, and the test/reset button is simple to use for regular checks. I also love the sleek design—it fits seamlessly into my home decor without being obtrusive. Most importantly, the dual detection technology gives me and my family peace of mind, knowing we’re protected from both fire and harmful CO gas. I highly recommend this smoke and CO alarm to anyone looking for reliable, easy-to-use home safety equipment. It’s an investment in your safety you won’t regret!

[This review was collected as part of a promotion.] What a great smoke detector that is small and easy to install. I also love the 10 year warranty and the fact that it is CO detector as well. It is definitely loud and will alert if it is ever needed!

[This review was collected as part of a promotion.] Easy installation, I love the battery life is 10 years! Has a slim design not a big bulky thing. It’s nice that it’s a 2 in 1 detector….fire and carbon monoxide. I received this product as incentive for my honest opinion in this review.

[This review was collected as part of a promotion.] I like that it has a battery that boasts lasting 10 years but I don’t like that the whole device needs to be replaced as there’s no option for battery replacement. If you have a textured ceiling, for example a popcorn ceiling, it might not hang well. (I received a free sample from Influenster in exchange for my honest review)

[This review was collected as part of a promotion.] This smoke detector is easy to install and really works when needed. It’s super durable but not too sensitive. It will detect smoke but not simple odors. I love that it will last for years!

[This review was collected as part of a promotion.] I just wanted to first say that this is very easy to install and only took few minutes to hang on the wall. I like that this is a 2 in 1 product instead of having to have 2 separate ones hanging up. It seems very durable and beeps loud enough to alert you if there was ever a fire which is a very important factor. Only had this for a few weeks and all its a good product to have.

[This review was collected as part of a promotion.] Installation of this product was very simple and it.has the screws and wall anchers included. I like that you don't have to worry about changing the batteries also.

[This review was collected as part of a promotion.] The installation on this was quite simple. Just an electric screwdriver and you’re done. Seems very durable and accurate. It’s not too sensitive. So it’s not going off if you burn something in the oven.

[This review was collected as part of a promotion.] First, everything you need to install the alarm is included in the package. Second, installing it was super easy and the included instructions are straightforward. I am most excited about the sealed 10-year battery—the battery is supposed to last for 10 years and then you buy a new unit. I love that this unit is low maintenence and we do not have to change batteries as frequently as I’m used to. The alarm, as expected, is loud (based on the test feature), and would definitely rouse anyone in my family from the deepest slumber. I also love that it’s another unit in our house that can detect carbon monoxide. Everyone should have a carbon monoxide alarm in their house and on each floor!

[This review was collected as part of a promotion.] Love this 2 in 1 smoke detector and carbon dioxide. 10 year battery life makes me feel safe for sure! Installation was super quick and easy. Directions were easy to follow. It’s loud!!!!!

I ordered two SMC0210 alarms and instead received two SMC100 alarms, which are an inferior and cheaper product.

[This review was collected as part of a promotion.] The First Alert 10-Year Battery 2-in-1 Smoke & CO Alarm is a solid investment for home safety. The sealed 10-year battery means no replacements or late-night chirps. Its dual detection covers both smoke and CO, eliminating the need for separate devices. The slim design blends well, and installation is quick with no wiring required. The alarm is loud and clear, with voice alerts for added clarity. Reliable, low-maintenance, and efficient—exactly what I needed.
