It only took me a couple minutes to get it to work. You plug it in, push the power button, and make sure the light is on. Then download the app and you're good to go. I bought this before a family vacation. It allowed me to turn on/off the lights when we weren't home. I also used it for my slow cooker. I work full time and some days I barely have time to cook dinner. After I got this smart plug, I can turn on the slow cooker at 2pm so when I get home the food is perfect to eat. A must have item! Highly recommended!
