  • Easyto Use
Style: Home Alarm (12 pcs)
Noce color, matched my new windows so that they are almost not noticeable. Easy to assemble, just add the batteries, peel and stick both parts on the window. Arming initial noise is annoying but you know it is ready to alert and activate.

  • Ugh
Style: Home Alarm (12 pcs)
It comes on but I can't stop it from beeping even when the other part is next to it

  • Does not worth buying
Style: Home Alarm (12 pcs)
There are two issues with this product: 1. The adhesive is very weak, which leads to the items to fall down from their position. Once this happens, and if the unit is not broken, the alarm goes off. Not a desirable result... 2. Once the alarm goes off, it disturbs the people of the house, though it's not strong enough to alarm anyone out of the unit. Bottom line - I wouldn't recommend this product. It's inexpensive, though doesn't worth the little money you pay for it. ... show more

  • Good
Style: Home Alarm (12 pcs)
This is a good product to have. The alarm has a high volume and can be heard from any location in a house or apartment. The quality is the only downfall yet, it is worth ordering.

  • Door Window Burglar Alarm Sensors
Style: Home Alarm (12 pcs)
"Door Window Burglar Alarm Sensors" are a great back-up system during electric, and WiFi outages. These alarm sirens are loud enough to wake homeowners / home renters from sleep, and loud enough to signal neighbors that a home invasion is in-progress to call for help.
