Fantastic for the price

"Two year old son has learned to open doors. So I placed one of these on every door. I set them so Alexa tells me what door is open and when it's closed. It also alerts me via phone . So while at work I'm aware of my doors . It doesn't set off an alarm or sound to cause my dogs to bark every time"

Great for notifications while away

"This product is amazing for what it's for. It works great as a door sensor that sends notifications when the door is opened. The notifications will be delivered to your device even miles away! I would highly recommend this product to anyone looking for a reasonably priced sensor for a door or window."

Very useful

"I purchased two of these. I use one of them in a gun cabinet. Very easy to install and set up with the Linkstyle app on my phone. I tested it. Got an immediate notification sent to my phone, that the gun Cabinet has been opened. The other sensor is on the Bar door."
