    Extremely quick shipping, good product
    Extremely quick shipping, good product. However it is a shame this cannot be stocked on the normal shelves in the stores.

    A God send for a person with hearing loss, a true life saver
    A God send for a person with hearing loss. Regular smoke alarms are completely ineffective if you cannot hear. They also need to be mounted on the ceiling which is extremely difficult for older individuals. This plug-in strobe alarm is a real life saver.

    Great product
    I had priced this from many sites and stores. This is the best price that I found and it works perfectly.

    Wireless Smoke Detectors work great!
    We paid over $1000 to hard-wire three smoke detectors in my son's condo - not to mention the drywall damage we had to repair - so when we purchased an older home that had NO smoke detectors in it - we cringed. This was a perfect solution and only cost us $249 for 10 with the promotion! They were relatively inexpensive and VERY easy to install. When triggered they ALL go off as if they were hardwired together. We highly recommend this product!

    Great Product
    Had to replace all of my smoke alarms as they were expired. Found this product to be easy to install. Loved the fact that they provided adapters so did not have to re-wire. Would recommend.

    made replacing my fireX simple
    Kidde bought out fireX and those were the detectors I had to replace. The adapter allowed me to simple replace the base by loosening two screws and replacing old base with the new one and then the adapter allowed me to use the old harness and not have to replace it. The only hard part was connecting the adapter to the new detector. Even when I pinched the new adapter to connect it I found I had to use a small flat edge screw driver to make the connection but after the first one all the others ... read more went in smoothly. Easy to install and saved me time.

    A good product well priced
    I purchased this to replace the old model 1275 (6 units). Installation took about 20 minutes since the 1275 bracket mounting holes were compatible with the new unit. Also the 1275 wire harness was compatible with the new unit so no need to do any rewiring. Housing was easy to mount on the mounting bracket. There is no cotter pin to worry about dropping and losing. Easy access battery compartment is great.

    great tool
    20 volt drill is lighter than my 18 volt one and has more power and last longer. Very happy with product and warranty. I recommend this product to anyone who needs portable power.

    A Good Smoke Detector
    The smoke detector was easy to install and having a built in, long life battery is a nice feature. Visually it is attractive. My only complaint is that it has a smaller footprint than my old Kidde smoke detector. Requires some paint touch-up. Contains only one detector type

    Easy installation
    I found these very easy to install. I purchased two packs (4 alarms) I managed to install all four in fifteen minutes. Ten years without that annoying low battery chirp sounds great to me. I have had one "false alarm" about a month after installation. The alarm is installed 3 feet from our bathroom and as far as I can tell the steam from the bathroom triggered it. That's really the only reason for 4 star rating.

    This product needs to be in stores
    As a retired firefighter and home fire safety educator, I am dismayed at the lack of quality fire/smoke detection products carried in-store. This particular unit is a dual sensor, meaning it can detect smoke/fire in two different methods, thereby giving a homeowner a greater level of security. Nothing beats an overall fire safety plan, but fire/smoke detector units like this are a big key in that plan. As for the detector itself, I like the fact that it uses AA batteries and is very easy to ... read more install. If you haven't replaced the fire/smoke detectors in your home within the last ten years, you NEED TO DO SO! Technology changes and the newer models are much more efficient than older ones. Remember, the life you save may be yours or your loved ones!

    Easy to mount.... Batteries included...
    Was able to install the detectors in my 3 rooms without any problems... Ran them through the tests (smoke and "test") features without problems. Good buy and a good product...

    Smoke Alarms
    Bought 3 of them for the bedrooms to bring the house up to newer, revised county code after replacing the water heater with a tankless model. Physically, very easy to install, check and test after reading up on where NOT to place them when dealing with bathroom proximity, vents, and ceiling fans. The two batteries seem to be easy to replace when required, after you've been alerted to that need. The only thing I see that I would prefer otherwise is the periodic flashing alert's very ... read more small and even in a darkened room, not all that easy to see. I could be a bit larger and/or brighter. But - here's hoping they're never needed for their intended purpose.

    Quick, easy installation
    I replaced older units that had been installed 15 years ago. Of the 13 units being replaced, two had problems with the wiring harness fitting into the smoke detector. A call to Home Depot had a new unit sent. The other unit was replaced in the local store. Should you purchase these units, make sure you test that the wiring harness connector will fit into the smoke detector.

    Very loud and great smoke alarm.
    I had to replace another in our 14 ft tall and very hot attic that most likely went bad from all the sawing I do up there in my shop. I was disappointed at first because although my old one had the same product number but different wiring plug. Then I looked in the box and there was a new plug with complete wiring instructions. Two minute job. I lit a match below it and it was so sensitive I didn't even have to climb up the ladder to test it. Quite satisfied :)

    easy to install
    This smoke detector was a replacement for one that went bad. It was very easy to install . I like that it has a backup battery which the old one didn't... I would recommend this product!!!

    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.

    Simple exchange with old devices!
    Replaced 6 old devices within 30 minutes due to the provided adapter. I have had to return 2 devices within 2 weeks due to false alarms. Hopefully the problem is solved.

    Product just as advertised
    Our old smoke detectors were 16 years old and seemed to be fine, but a home inspector (with no financial incentive) suggested they should be replaced periodically. So, we replaced 4 of them in our home. Also, we did not have a CO alarm. So, we got two of those as well (same brand). The installation could not have been easier. They fit on the same bases (even though we changed most of them due to discoloring) and used the same snap-together connectors. They were also easy to test. We are very pleased.
