Door and Window Sensor
It was easy to install but this product didn't fit my needs. The alarm was loud enough but I needed a device that would give me the option of using a loud alarm or a simple chime to indicate that the door or window had been opened. Although the product description says there is a chime feature, for me, the chime was only an initial sound and then the loud alarm would sound until the door or window was closed.

Really LOUD!
Easy to install and use, just decided not to use for my purpose which was to sound a reminder alarm for my kids and nieces and nephews to close the door during the summer. Waaaay too loud!
