Customer Reviews:

  • GREAT BUY - Try using velcro to install these, Batteries will be easier to replace, PLAN POSSIBLE BATTERY REPLACEMENT AT RECEIPT
    GREAT price even though I had to replace some batteries on receipt - AFTERALL, this is a discontinued product. This is a 4-pack of ALARMS. Two alarms worked great right out of pkg. One had weak batteries, One had dead batteries. Fortunately, I had ordered a 50 pack of batteries for less than $6 total with FREE shipping off Amazon (from hobbytoolsupply). I'm glad I got these alarms but batteries are kinda frustrating to replace. I had to use tweezers to remove dead batteries BUT this was even before I even stuck unit to the door. So I decide "WHY NOT USE VELCRO TO ATTACH INSTEAD OF STICKY BACK?? That way batteries will be much easier to manipulate when it is time to change. I will probably ALSO try the "door stop" type alarm that uses a 9-volt battery. I can just pick up the 9-volt batteries at Wallyworld. Also, alarms I received are different from those pictured but they ARE FirstAlert products. Even with the battery hassle, I still recommend because the cost is super low. ...more info

  • Sleep Soundly at Night Again
    I've owned this product for 2 years now and have never had a problem with them. They are great to let you know that someone has left the house on the chime setting and give a great piece of mind at night on the alarm setting. Unlike others, mine have never fallen off, in fact I'm worried about how I'm goin to get them off when I move! That's how sturdy they are!! ...more info

  • Window alarms
    I really like these, they're a little smaller than I first thought but they are loud enough to do the job I believe. Every once in awhile I open a window and the alarm goes off, scaring the heck out of me but at least I know they're working!...more info
  • window alarms
    these units work great, purchased for side porch windows that cannot be seen from inside home. Have set them off by mistake when opening window to get fresh air on porch. Good way to test and I know they will work if an intruder ever tries to enter.

  • Worth the price...
    A few years ago there were several break-ins around my neighborhood. After checking on some monitored alarm services and learning I couldn't afford to have sensors on all entry points, I decided to try these.

    I purchased a total of 50 and three of those did not work at all. I chalked that up to "getting what I paid for". They ARE cheap!

    They are VERY easy to install. Unfortunately, they don't stay installed. Within the first 24 hours, some had already come loose. Within a month, at least half had been put back with duct tape.

    I was not able to install these on one of my doors. I could have put one on the outside of the door, but not the inside. Maybe my door is just inside-out. Or maybe these don't work on ALL doors and windows.

    On the positive side, they ARE loud. They worked well enough to give me a lot more peace of mind and that was exactly what I was looking for. A few are still working and loud after more than 2 years.

    I would probably look for a different brand to try next time, but these did live up to my expectations. ...more info
