    For me the best choice
    Chose this because I wanted low cost, photoelectric, and a replaceable battery. It replaced another Kidde with a so-called 10 year sealed battery that lasted about 5 years and typically started chirping about battery failure at 3 AM. I have programmed my iPhone to remind me to preemptively replace the 9V battery in 2 years.

    Does what it says!
    Excellent kitchen smoke alarm! Since replacing our old one that went off any time we sauteed anything in our kitchen, this one stays quiet but goes right off when we test it with an open flame.

    Very economical
    I needed several fire alarms for a rental property and these were very economical to buy this way. they are also small which is nice so not too obtrusive in the rooms.

    The product appeared to be what I needed
    I was looking for an economical solution to replacing smoke detectors in a duplex I own. The box of six detectors seems to be exactly what I needed: an economical, easy-to-install product.

    Great smoke/fire alarm for the price
    This is a great smoke/fire alarm for the price. I was happy a larger contractor pack was offered.

    Up to date protection, easy to install
    This was a replacement for a 10 year old unit, it was a piece of cake to put in. The bezel that mounts to the ceiling was just slightly larger than the original so it covered the slight indent left by the original. Honestly I think this took about 10 minutes to have fully operational, that included opening the package and glancing at the instructions.

    There are not many wired smike detectors out there with Lithium batteries
    Exactly what I wanted at a good price. I had been looking all over for wired smike detectors with litho=ium battery back ups. These were exactle what I needed, easy to install and no replacing batteries every year.

    Best Smoke Alarm on the Planet
    Best smoke alarm on the planet. I have had clients put these in a number of houses that were getting false alarms all the time. Now they have none. In houses where alarms had been ripped out of the ceilings because of false alarms, now the alarms stay put, changing an unprotected house into a safe one. In my own house we had problems every week: humid days, neighbor firing up his wood boiler, dinner being ready, etc. Now we have no problems at all. Plus, I don't have to run around the house ... read more looking for a flashing light that tells me which unit is causing the alarm. A push of the button, on ANY alarm will cause only the offending alarm to beep, making it easy to find. This detector also solves the problem of alarms that are out of reach, as I can silence that alarm from one that is mounted at a more convenient height. Their website says this alarm, according to a university study, is the fastest responding alarm out there to detect fast flaming fires, which you would get an ionization alarm for. It responds 87% faster (than required?) for slow smoldering fires, which you would get an ionization alarm for. Better than both kinds, and the "Microprocessor Intelligence" might be just a cool way to market it, but it really did eliminate all the false alarms in my home, and my clients' homes.

    Good product, long shipping time.
    This was a replacement piece in my already wired system, so it was super easy to install. Almost a week long shipping time seems a little ridiculous for such a small item though.

    Good Smoke Alarm
    This is a good smoke alarm for the price. Easy to install; I didn't hard-wire mine. I like the fact that you can easily change the battery w/o having to take the unit apart.

    120V W/ 9V Back-up with Easy Install Wire Harness
    Needed to replace an old unit. This was very easy to install. Simply mount the plate on the electrical box and then hook up the wire harness. Plug the wire harness into the unit and a slight turn attaches it to the mounting plate. Not only is this 120Volt that can be wired in sequence with other units, but it also has a 9 volt battery back-up. The ease of mounting and the wire harness will make it quick and easy to replace the battery as well. It also looks nice on the ceiling.

    Great product
    I installed 3 of these to replace older smoke detectors and wanted the dual sensor versus just having one type. Installation was easy and in my case, just 3 wires and it was done (as far as the wiring). I had to change the ring that the alarm attaches to since the new one was bigger but that was easy as well.

    Nice features and easy to install
    The combination of Photo and Ionization smoke detetction with AC power and battery back-up is nice. I bought three of these to replace the original Firex wired smoke alarms in my 18 year old house. Installation was simple. My only complaint is that the smoke alarm is a bit large. You also need to remove the smoke detector from the cieling to replace the backup battery. Overall a nice smoke detector.

    six were not enough
    it wasn't clear in the write up but these detectors have no battery. This was actually good because two of the detectors I replaced were so high up I had to bring in my extension ladder to get to them--a real pain when the battery starts chirping.

    like home depot online
    The smoke detectors were a direct replacement for my old ones. Found them on the home Depot online and ordered them. Two days later they are here and installed. The smoke detectors are great but home depot online is even better.

    Wireless Kidde Smoke Alarms
    The 3 pack concept for the battery operated Kidde wireless smoke alarm allowed me to save money over buying single battery operated alarms. They arrived from Home Depot on time and in good shape. Although the alarms cover fire detection using the ionization principle, they do not include a carbon monoxide detection feature. It would be helpful if Kidde clarifies which AC powered units are compatible with these wireless alarms. Not sure if there is broad compatibility.

    Easy to install
    I needed to replace a smoke alarm that was randomly going off. The old one was around 10 years old, and just worn out. I purchased this smoke alarm and was able to disconnect the old one and replace it with the new one easily. I have NO experience with smoke detectors, electrical parts, etc, but this was easy enough a novice could do it in under 10 minutes.

    Easy to Install
    This is a very easy replacement for old smoke alarms. It has adapter plugs that work with other connections. I did not use them but thought it was a nice addition for people who may be uncomfortable with touching electrical wires.

    Good replacement or new smoke alarms
    Very easy to install and good to have the battery compartment on the face so one doesn't have to remove the whole unit in order to change the battery.
