    [This review was collected as part of a promotion.] It's really easy to install. Simple instructions. I have had it up and working for over a month now. Seems to be working great and has no hassle at all. Would definitely buy another one for the other side of the house.
      Easy installation and setup
      [This review was collected as part of a promotion.] This smoke alarm is actually very easy to install and seems like it will last for years to come. It has voice alerts and also a guaranteed 10 year sealed battery which is nice to avoid those annoying chirps in the middle of the night. I feel incredibly safe knowing that it is there. The casing of the unit is constructed of hard plastic and feels very solid. It is sleek looking and not terribly big and gaudy looking like some units from the past. Set up is a breeze and it even has the ability to interconnect with other kid units in your home, which is comforting knowing they can be synced up. I would absolutely purchase another. Kidde is a trusted name in smoke alarm and CO2 detectorsane I would recommend to anyone.
        Good so far
        [This review was collected as part of a promotion.] I gave this to my husband to test as he would have been a better tester than myself. He uses it in his 3d printing room and has like how it performs so far. It was super easy to install, and the design didn't disrupt the room design. I can't review in detection as we haven't had a real-life situation (he tested it with a fake situation) but overall seems to work reliably.
          Simple and portable
          [This review was collected as part of a promotion.] I received this smoke detector complimentary of Influenster in exchange for my honest feedback. I am excited to try this smoke detector in my home. Although we have not had any incidents trigger the alarm, I really appreciate that it has a 10-year battery, voice alerts so you know which smoke detector is alarming, and it just twists onto the holding bracket. Very simple to use - perfect for any home, rental (unscrew it and take it with you when you leave!), or even mobile home / RV.
            Last for 10years
            [This review was collected as part of a promotion.] I received this product free from Influenster to try and review. It is the Kiddie Detect Smoke Alarm. I love that you don’t need to change the batteries and that it last for 10 years. No more annoying chirping when the batteries are low.
              Will definitely be ordering more of these!
              [This review was collected as part of a promotion.] LOVE that I don’t need to change the battery in this!!! There is literally nothing I hate more than when the battery is low in my smoke detector and it beeps all day. I have very tall ceilings so it’s difficult to constantly change batteries and with this unit, i only had to put it up once and now I don’t have to think about it for 10 years!
                Great Products
                [This review was collected as part of a promotion.] DETECT Smoke Alarm 10-year Battery Powered and Voice Alerts is a superior line of high quality Smoke Alarm products that's very effective and is absolutely a Fabulously Awesome Products. Highly recommended
                  [This review was collected as part of a promotion.] This smoke detector was easy to install and seems pretty simple and straightforward. I’m impressed with the battery life. It seems durable and love the voice alert feature.
                    Must have
                    [This review was collected as part of a promotion.] Super easy installation, good size, and works nicely! My husband put it up and he said he felt like it was sturdy as well as easy to use! Thank you for making our homes safer
                      No Low Battery Chirps
                      [This review was collected as part of a promotion.] I received this Kidde smoke alarm to review. I love the simple look of this one. I really appreciate the the features of this smoke alarm. It has voice alerts and the best feature of this is that there are no low battery chirps that you get with older model some alarms.
