## Customer Reviews

### ⭐⭐⭐⭐⭐ Great product, easy to set up, work great.
*by W***E on July 31, 2025*

Product works perfectly. Used on my motorhome to control my outside lights. Paired with the app and easy setup.

### ⭐⭐⭐⭐⭐ Control anything from anywhere.
*by T***. on August 11, 2025*

These wifi relays are awesome they allow you to control anything from anywhere. For me they allow me to shut off my generator while im 150 miles away from home at work.

### ⭐⭐⭐⭐ Works great. Could use better instructions.
*by S***. on November 16, 2024*

Perfect for what I needed. Replaced a $145 relay that operated through a sim card that I was paying a monthly fee for. Was shocked by how small this was. If you have 2.4G wifi access where you'll be using this, it's the only way to go. Used it to activate a solenoid for the drop door on a hog trap. Used the 2nd channel to activate the deer feeder. Can activate either one from anywhere I have phone service. Can think of lots of stuff this little gem could be used for. Instructions could be a little clearer but if you're even using this thing, you're probably tech savvy enough to figure it out.
