Did exactly what I needed it to do. I will say the directions are a complete waste and if you try to follow them, you will not be able to synchronize the transmitter and the receiver. It’s only because of a previous Amazon review that had a video showing how to do it that I was able to get the system set up. After that, everything went very smoothly! I would highly recommend these, but make sure you watch the video review because the directions are worthless.

These things have to be basically touching in order for them to register being pulled apart. If they are an inch or more apart in the “normal†or closed position, then they do not sense when they’re pulled apart. I don’t even know what folks could put these on that’s that close together.

Hard to switch sounds product works but is a lot of messing around to get it programed. If you need simple this is not for you. Once set up operates as should but alot of wasted time.

This is just amazing. I have had a problem with tardy freshman sneaking in or out of class but this stops it cold. Some one gets a text from a friend to leave class and start trouble, well they can't leave without a loud alarm going off. A student tries to say they were already in the classroom when taking attendance. NOPE this thing goes off and the kid just looks at you dumbstruck. This fixes so many problems in the post covid 21st C classroom that I would recomend it for every classroom. I LOVE IT!!!!!!

They perform exactly as advertised. Pair and noise selection instruction slightly confusing but easy to figure out.
