Essential Info

Techko’s S183 Ultra Slim Safety Entry Alarm can provide valuable protection for your home or property by detecting the unauthorized opening of a door, sliding window or cabinet door, all in a low-profile design. This can be mounted on almost any door or window setup and requires no wiring or special installation. When the door or window is opened, the alarm’s switch detector sounds the built-in db alarm. After 60 seconds, the alarm will reset itself. To arm or disarm the system, there is a convenient slide switch on the side of the unit.
Important notes:
Defective exchanges for identical item within 30 days of purchase. After 30 days, please contact the manufacturer.

These work just as they should. :-)

Smarthome has great customer service. They replaced my first purchase, which was defective, promptly and at no charge. The product itself is built somewhat flimsy. The on/off switch doesn't always work right and feels very cheap and fragile. The unit does work as advertised when you can get the switch to turn it on.

The product works but is cheaply made. The switch is chinsy. The first one I received was defective. Customer service provided a new one at no cost to me, which was wonderful!

Once the door is opened it has a long delay before the alarm goes off. It gives an intruder plenty of time to turn off the device before the alarm goes off.
