I bought my first Echo (original) in February 2016 and (anticipating smart home use) also got a couple of WiFi sockets available at the time ordered -Fi. . They came from an American company and are still used today. The problem was that they were too big and didn't have much power. I recently bought a "fryer" but while it wasn't cheap it didn't have an on/off switch and had to unplug it every time I used it. Very uncool design. So I bought one of these switches to use as a switch for this device. The challenge was to find a WiFi switch that could handle the current. The fryer has a rated output of 1700 watts. Yes, I know it's irrelevant. And these switches are rated at 1875 watts. So I dared. I bought a pair and use the other with a radiator in my den (1500 watts). Both work very well with these switches. But that's not all, the switches were the easiest to set up of the (now 15) switches I have around the house, and they connect to Echo/Alexa automatically. They can be turned on and off physically by pressing a button, or with the phone app, or with Alexa commands. Perfect! Of all the switches I've bought in the last four years, these are (surprisingly) the best. In addition, they are much cheaper than their domestic counterparts. If my opinion on this changes I will update this review but for now I am completely satisfied. Great price, easy operation and high performance. Addendum 07/08/21: Just bought #3. All of the above points remain in effect. I am using it on a large fan with high starting current but moderate running current. The plugin works excellently on both the iPhone and Alexa. Still the best value for money in an outlet that doesn't require a separate hub to operate.
