Window alarms 
2008-07-14
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!
Sleep Soundly at Night Again 2008-06-19
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!!

First Alert Instant Door Window Sensor Alarm System
I received 4 alarms and new batteries to replace all of them 2 times. I called because 2 didn't work and received 4 more with new batteries for the 4 alarms. Great service from this company.

Alarm Sensor review 2008-02-05
I am pleased with this product. It did take longer to arrive than I thought it would (over a week). I had to replace batteries in 3 of the units. But they seem to do what they are designed to do and I am glad I purchased them.
window / door alarms 2008-01-08
These alarms work well, but I'd like them to be louder. They do come with everything you need to install them and get them working, and are very reasonably priced.

Loud and easy to install 2007-12-10
Very loud. But not loud enough for the Florida Building Code = cannot be used as a pool alarm.
