Installation:
These smoke detectors were easy to install for me. Each detector came with its own hardwire to use. However, since my old detectors were already hardwired, I just needed to plug it in for it to work. One thing that I had to do though was unscrew the old plate from the old detector and install the new plate. This actually took the longest as unscrewing took a little bit because of the long screws. Something to note: These detectors do not come with screws for the plate so if you need screws go to Home Depot first or somewhere similar. These detectors also come with instructions so they should be pretty easy to follow if needed.
One of the cons of these detectors is that the battery seems to be jammed in pretty good. It's super hard to take the battery out unless you un-attach the smoke detector from the ceiling/wall. Even then it is pretty hard to take out. I'm not looking forward to the day that I have to change the battery in the middle of the night for these. Hopefully that won't be for a while. One of the other things I noticed when installing these alarms was that one randomly went off after I installed one of them. Another one started beeping with the low battery sound right away and went away after 5 minutes. I don't know if it's because of bad design or defective product but they seem fine now and have the green light. Just something I thought I should mention for those looking to buy this product.
Usage/Function/Testing:
After installing these, you can test the alarm by using the "test" button on the detector. Make sure to have ear protection or something as the alarm going off can be really loud especially if you are just right next to it. It was loud enough for me to hear throughout the house. Make sure the alarm also has a steady green light as this means that it is functioning correctly. Overall, easy to use and we'll see how long this lasts before it needs to be changed.
I recommend this product to anyone who needs a replacement of their carbon/smoke detector. This took only a few minutes to install and was relatively easy. Only a few cons as I mentioned above which is why I gave this 4 stars instead of 5.
