But the design of the receivers/alarms that plug in are just slightly too large and slightly block the second electrical outlet of normal 2-outlet sockets so you can't plug in anything else in the second socket

I was afraid that each button would only activate one receiver/alarm, but as it turns out, BOTH buttons activate all 3 receivers, which is exactly what I wanted!

I needed 3 receiver/alarms and so this kit was perfect

My workshop is about 100 feet from the house and her panic buttons activate the receiver/alarm out there perfectly
