Best Smoke Detectors & Fire Alarms of 2025

"I appreciate the long-lasting 10-year battery. It's such a relief to avoid changing batteries every year!"

"I was surprised by how quick and easy the installation was. The price is really reasonable too!"

"I was skeptical at first due to the smaller size, but I actually prefer it now. The design is sleek and it works just as well!"

"I have 7 interconnected alarms in my home. Whenever one goes off, they all do, which is a must-have safety feature. I used to miss alarms in different rooms, but now I’m always aware. I had an incident with incense causing smoke, and it was reassuring that the alarms alerted me throughout the house. The X-Sense detectors are worth the investment for their interconnectivity. I appreciate the easy installation and quality parts. Although the Nest Protect has some extra features, the value of X-Sense is hard to beat."

"I strongly recommend this critical safety product for anyone wanting to ensure their family is protected from fire and carbon monoxide. The 10-year battery life is a great feature since it means you won't have to worry about changing it frequently. The instructions are straightforward, and the warning signals are easy to understand. It’s definitely one of my top recommendations!"

"We replaced old detectors with 9 XSense alarms for our entire home except for bathrooms. I opted to install them on the ceiling, following best placement guidelines. The installation was mostly straightforward, but I learned that the bracket may not line up perfectly, requiring some adjustments. Pairing them was a breeze after I reread the manual. I’m confident these alarms will wake us up during emergencies, and I’m glad they should last about 10 years before needing replacement. Overall, I'm pleased with my purchase and feel much safer now!"

"I found the installation to be super easy and the price is much more reasonable compared to in-store options. It works great!"

"I ordered six of these alarms and they are perfect. The installation process was a breeze!"

"I replaced my 20-year-old units with these new ones and found the installation process to be easy. I appreciate the option to use them separately or tie them together."

"I found these smoke detectors to be small and easy to install. The included batteries weren't great, so I opted for better quality ones that worked perfectly. I truly hope we never have to use them!"

"Overall, these fire alarms have mostly met my expectations. I got six units; four worked flawlessly, but two went off randomly. Thankfully, I only needed four, so it wasn't a big deal. The functioning alarms give me peace of mind with their reliable performance."

"I appreciate how well the batteries are holding up. I mounted the alarms using magnets for convenience, but I’m a bit concerned since my garage can dip below the recommended temperature. Still, I’d say it’s a good purchase overall."

"I found the product super easy to install and it came with all necessary items to operate! The batteries were included and I love that they last 10 years! There is a loud beep at the beginning, but it's just to ensure that it is working properly!"

"After installing these six years ago, I noticed the batteries are starting to fail—they didn’t last the 10 years as advertised. Despite this, I'm still purchasing more because they work well and it's easier to replace them than to switch to another brand."

"I had this product for over 10 years and recently bought replacements for my previous two. I'm very satisfied with the quality and overall product!"

"I noticed this model is quite different from earlier ones. It was more expensive, but I found the installation to be quite easy. The manual is extensive and informative, even providing guidance on how to silence the alarm for 10 minutes if needed."

"After hearing great things about these alarms, I purchased one without realizing my previous ones were disabled due to constant chirping. Installing it was a bit tricky, but once I got it on, I tested it, and it works great. It has a long 10-year lifespan, and I love the bright green color and the button to disable the alarm. Overall, it feels worry-free!"

"I chose Kidde because of its stellar reputation. I appreciate that there's no need for annual battery changes with the built-in battery. These detectors last for 10 years, which is appealing. I usually test mine every six months, and they've exceeded my expectations over the years!"

"I found the price to be excellent, and the delivery was prompt. I had to replace the bezel but the replacement fit perfectly. I opted for Amazon Basics 9V lithium batteries, which should last ten years, making them worth the cost!"

"For me, the installation was a breeze. The alarm accuracy is impressive, and I haven't faced any false alarms. I really like the bright white color; it looks fantastic in my home!"

"After the fire department checked my mom's alarms, I replaced four smoke detectors. These were more affordable than those at Home Depot, and the installation was very straightforward since I used existing wiring. I'm satisfied so far!"

"I absolutely love the smallness of these detectors! The sticky patches make installation a breeze, and the fact that they come with batteries is a huge plus. They are very loud for their size and work great!"

"These detectors are easy to install and function perfectly. I've had them since June without any issues. The quality is very good, making them a great value."

"I found these to be very sensitive; they go off with the slightest smoke in my kitchen. The red light that flashes every 30 seconds can be distracting, especially for light sleepers. But as a heavy sleeper, they work perfectly for me!"

"This was only my second time installing smoke detectors. I learned that replacing the wired harness isn't difficult at all. After some trial and error with the circuit breakers, I successfully installed the new detectors. They all worked perfectly after installation, and it passed the home inspector's check!"

"I had my grandson install four of these smoke detectors across the house, and he found them easy to handle. They look so much better than the old ones, and I'm really pleased with the upgrade!"

"Initially, I faced issues with false alarms and had to replace them several times, which was quite disappointing. Ultimately, I had to give up on them as they all failed."
