    Nice features and good price.
    Easy test and I like the escape light feature. Had to replace the original wiring connector with the one that came with the unit but it was an easy fix. Another nice feature, it comes with a Duracell 9V battery. Item looks nice and so far no issues.

    Good product
    Was easy to install and test. Battery placement is convenient. The only issue I have is that every so often each of the alarms will chime 3 times for no reason. It doesn't seem to be the same alarm, it is all of them. Not sure what that is about, but we're getting used to it.

    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.

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

    Does what it's supposed to
    What can you say about a smoke detector. It does what it should. It's very loud for those that can hear, and offers a very bright strobe to help the deaf. The price at Home Depot was the best I could find.

    Necessity, but last less than 10 yeqars
    Purchased this particular smoke alarm again because it was a direct replacement and I didn't have to change the mounting ring. The first one I purchased only lasted 3 years before it started to chirp indicating replacement. It is a good alarm, easy to mount, but don't expect to leave it in place for 10 years.

    Good buy
    I am glad I bought this double pack whcih is cheaper then the singles. The way it works the batteries are in standby mode until you activate them. Mount the bracket and twist the alarm on and you hear a beep. The battery is then activated. The 10 years then starts. Once mounted and you hear the beep, then they want you to press the TEST button so it beeps again. DO NOT unscrew it from the base. That will deplete the battery. Once mounted let it mounted. To silence press the silenece button do ... read more NOT unscrew from bracket. I put a mark on the silence button so it is easy to spot as the test and the silence button look alike, try reading the words when mounted.

    Good deal
    Smoke alarms are necessary in every household, and this 3-pack makes it easy to place alarms in multiple areas around the house. They are affordable and easy to install.

    Installs easily
    Installs easily and seems to work pretty well. The instructions actually make it seem more complicated than it really is. The alarm is nice and loud, although the talking feature seems more of a gimmick. Somewhat on the pricey side.

    Great units easy to install and giving better protection for multiple areas
    The units were quite easy to program and install for the wireless connection. The video instructions on the CD were good. We have noticed that the unit near the kitchen, does not have the many nuisance alarms that our former unit (of another type) had. In our place, the wireless connection with alarm signals at all units are important, as the garage is under the living quarters. An alarm sounding in the garage would probably not be heard in the bedrooms, if it were not for the wireless ... read more connectivity in this system.

    keeping my Family Save
    The smoke detectors was easy to program. I know that we will be safe if there was to be a fire in our home,because its loud and is placed in each room of the home. The price wasn't bad because it came in a two pack with a saving of $15 each.

    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.

    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.

    Smoke Detectors
    Included adapters that meant I didn't have to redo the hardwiring already in place with my old detectors. Ability to check and change batteries without taking the detector down from the wall also a plus. Very pleased with this product.

    Nice!
    A no frills smoke alarm that installs in just a couple of minutes and has a great price. I got this for our camper and it's perfect. A little smaller than the old one and it comes with a battery as well. Awesome value.

    It could save your life!
    I purchased these on an impulse buy. I was walking down the water heater isle and saw these at such a great price. I figure I should pick up a few and install them throughout the house. I install them that weekend and forget about them. A few months later, I'm in my bedroom and I hear a loud beeping coming from downstairs. I go to investigate and find my living room full of smoke. The smoke was caused by frayed wires on a home entertainment system. If it wasn't for this alarm, the smoke would go ... read more unnoticed leading to an actual fire. At this price, I would say to buy one for your friends and relatives as well. There aren't many gifts that you can give that can save someones life.

    Can't beat the price
    Works fine. No fancy frills, but who needs them? At the price, you can afford to put more of them around the house.

    Works!
    Yay! I didn't have to spend $375 to get a Masterguard smoke alarm. This product is the same product as the Masterguard rip offs. Thank you Gentex.

    The product is reliable and performs as expected.
    The smoke detectors perform as needed. They are easy to install and also to test periodically.
