    I ordered six smoke detectors based on some information from a neighbor. I should have done more research. I spoke with SmokeAlert Customer Support and they were very helpful.

    I needed a replacement fire alarm for my home and after looking for a good price with free shipping I ordered from SmokeAlert. I received exactly what I ordered, it was easy to install, and arrived quickly.

  26. Charles B –

    Replaced all my 9120B alarms. The BRK I had were 11 years old. I stuck with BRK because I feel very comfortable and safe with them.

  27. Anonymous –

    The alarms ordered replaced the same model that had been in service in my home for 10 years. Therefore, installation was easy since all I had to do was unplug the old unit and plug in the new one. I guess you only really know how good the unit is if you have a fire and the alarm sounds. I’ve not had any problems with this model alarm in the past and don’t anticipate any in the future. It was nice that a battery was included.

    I wanted a smoke alarm that would fit the footprint and wiring of an existing, outdated smoke alarm. The First Alert 9120B fit perfectly and each was installed in less than 10 minutes. This smoke alarm also guards against carbon monoxide. A great buy!

    Smoke Alert has become my go to company when I need any First Alert BRK alarms. The price is the best I have found and shipping is free and they carry alarms that most stores don’t carry. They ship timely and my orders are accurate to what I receive.

  49. RICHARD Withers –

    You are the best

  50. robert calnen –

    worked like a champ…direct replacement of a 10+year
    old 9120B alarm that probably needed an internal cleaning. chirp is disgusting but the new unit fit perfectly and made me happy that it is still in production. thank you, chirp is gone!

  51. Shera Pender –

    I have full trust in this product, we have used them and they work every time. Even if there is smoke from the oven!

  54. Ronald Hepler –

    I needed to replace a 22 year old unit that began spurious allerts. Teh new unit was Plug & Play, I didn’t even have to change the base. Perfect.

  55. FJH –

    I have bought several smoke/CO detectors from Smoke Alert. Their low prices and quick delivery keep me coming back. This time, I had trouble submitting the order online, but their team in the office placed the order for me. There was some trouble getting through to sales, but I will chalk it up as a fluke.

  56. Spencer Hancock –

    Good products, competitive prices and fast shipping, what more could you ask for?

  57. BengiPC –

    Pretty easy, just remove old unit, remove old mount piece, screw in new mount and plug in the wiring. The hardest part is disconnecting the old wiring plug. line up the new unit, push it up and twrist till it locks in position.

  58. Michael EauClaire –

    Great value and fast shipment
