  • Carbon monoxide and smoke detectors
Style: RF Interconnected Model Size: 6-Pack
This is a well built carbon monoxide and smoke detector combined, it has 10 years of life built in battery in each sensor. Install was easy and activating connecting all 6 sensors to each other is a helpful and great safety feature. Price for pack of 6 was very reasonable compared to others sold at major stores ... show more

  • These are fantastic CO/Fire detectors.
Style: RF Interconnected Model Size: 3-Pack
I have 7 of these in my home. Each is interconnected so when one goes off, they all go off. This is a must have for any home and should be standard. Many times in the past, I have missed a smoke alarm going off because I was in the shop or some other part of the house where an alarm is challenging to hear. These mitigate situations where you are not aware. The other day, I had lit a stick of incense and placed it in an old planter pot that had dirt in it. Well, it managed to burn the dirt and melt the plastic liner in the pot. I was in the shop at the time and when the kitchen detector went off, so did the one in the shop. The X-Sense detectors that link are a little more spendy, however I can say that the feature is well worth it. What I like: * Easy install * well made with quality parts. These not only look good but they also feel substantial * Interconnectivity! * No need to fool around with another app on my phone. I like the simplicity although I do like the Nest Protect’s ability to send a notification and turn off the HVAC if smoke is present. That’s a nice feature but the price point makes them difficult to justify the cost. I can get three XSense detectors for the price of one Nest Protect. * No subscription required. * has a visual display in addition to standard LED lights. Cons: * not able to send notifications in a smoke/fire/CO situation. I highly recommend these over the standard detectors that have been in use for a few decades now. Step up to the XSense and link them together! ... show more

  • Combo smoke and monoxide alarms
Style: Standalone Model Size: 5-Pack
These were easy to install, work great as advertised, and have a nice appearance.

  • Great so far!
Style: RF Interconnected Model Size: 6-Pack
Well we just got these to replace some that were very old and not interconnected. We got 9 (6 pack and 3 pack) to go in every room of the house except bathrooms (due to humidity). We have 9’ ceilings and the old ones hung on the wall right above the door frames ... after reading about best placement I chose to install these on the ceiling even though I’ll have to use a ladder to test. If you can’t place in the center of the room due to a fan make sure it’s at least 3’ away but not in the corners. Also it says at least 10’ from an oven or stove to prevent false alarms. This makes sense as our last kitchen was smaller and the alarm was about 5’ away from the oven and would go off every time I cooked and opened the oven. We used to joke that dinner was ready when the alarm went off. Anyway- these were easy to install but as another reviewer stated the bracket doesn’t line up with the top and you have to place the whole thing on the ceiling, hold the bracket and carefully remove the alarm without moving and install to get it facing the way you want. (I learned this after the first one was lightly off center) I used a push pin 📌 to help hold it in place until I got the first screw in. I did this alone but it might be helpful to have a second person to hand you the drill or screws or whatever. Thankfully my ladder had a tray on top. In the instructions I missed that you have to pair them manually and just assumed they would all talk to each other. Thankfully I questioned this and looked at the manual again. Pairing is super simple and only takes a few seconds. You can set up different zones too if you don’t want them all on the same group. I put mine all together. Take the first one and press button 4 times quickly then press second alarm twice quickly and they will blink some then beep and they are paired. Just repeat this process with an alarm from the group you want to add to. I already had mine installed so I had to take one around the house and pair them all to it but this would be a very simple process to pair them all before installing. To test the group hold the button in while you test. It will beep several times on the initiating alarm then the rest in the group will start beeping too. Warning this will be extremely loud! Ear plugs/muffs are recommended during this process. My dog was not happy with me after I went around the house making sure they are all alarming after pairing everything. I think I’ll put her outside first next time. Assuming these detect smoke and carbon monoxide accurately (I’ve not tested this other than hitting the test button) I’m confident that the entire house will alarm and wake us from a deep sleep if necessary! Did I mention that these are extremely loud? Also I’m glad these should last around 10 years or so because I figure in that time the technology may be more advanced and they’ll need to be replaced anyway. That way we won’t be stuck with some dinosaurs that are out dated like we were before these. So far I’m happy with my purchase and feel safer in my home. ... show more

  • Great
Style: Standalone Model Size: 3-Pack
I left a similar review on the Wi-Fi connected version so I will keep this short and sweet. I wanted to have some 'dumb' detectors for my bedrooms and smart ones for each floor. I like that at a glance they look the same so you don't have a weird looking mish-mash. Easy to setup, all hardware was included. Nicely packaged. The feel solid and look good. Very satisfied so far, the only thing I can't speak to is if they will last 10 years or not. ... show more

  • Terrific value smoke/CO detector
Style: Standalone Model Size: 1-Pack
Great smoke/CO detector, multi functional alarm that clearly pinpoints what the dangerous situation is in your home. Easy to install with a 10 year battery life, so you don’t need to keep track of changing out batteries. Perfect size, actually looks nice & streamlined
