Love these things! So easy to set up (instructions not only in English, but they MAKE SENSE!). Can rename each plug and easy to see on app. Turn on/off remotely, program for timer, even turn all on/off as you come home or leave. 3 prong so should work for most electronics (not sure I would put a high voltage draw item like a space heater on them, though). Haven't tried to "share" them on multiple phones (so my wife or kids can turn on/off as well), but instructions say can do, and everything else is living up to expectations.
UPDATED about 2 weeks later -- I wrote this review after setting up one plug. After pulling the rest out, I could never get one to pair (the pairing went super smooth on the first two, the third would never connect right). After about 4 days, the fourth plug wasn't responding to the app. At the same time, we downloaded a new app to connect our Echo to the plugs. The first two converted just as smoothly as before. The last two were doing the same thing (start into pairing, but would never make the connection). I contacted the company and they offered a refund for the two, but now am hoping the other two work long term. By the way ... works great with Alexa!
