4 WINDOW & DOOR BURGLAR INTRUDER ALARMS ALARM WIRELESS SENSOR

Ok for the price
These alarms work ok once you can get the battery cover off to pull out the tab. Also, the sticky pads weren't on the right surface for my particular needs. This was easily sorted with a spot of glue. The first set I used stopped working properly when the alarm wouldn't stop, even though the 2 parts were side by side.
