I had bought 2. After 8 months, one suddenly started disconnecting from the router, a problem that was temporarily fixed after a restart. Then it overheated excessively, so I unplugged it. I connected it to another socket near the router, did a reset, it worked for a while, and now when I plug it in, it doesn't turn on at all. Its advantage is that it works with the ewelink application, because I have many other components from the same company, and that it is affordable. However, it seems to be a risk. I would only buy it again solely because of the price. I have others from different companies like Belkin, much better.

Connected to Philips HUE Bridge (v2) instantly, faster than the Philips bulbs themselves.

Update 9 months later:
Removing one star. Both outlets, when left connected to the power supply for days (4-5), stop functioning, either through zigbee or the button. If you unplug and plug it back in, everything is fine (have you tried turning it off and on again??).
It's not a big deal, just makes it a bit inconvenient for certain uses. It works fine for the lights on the kitchen counter. But if you want to control a remote house that you visit every 10 days or have it turn off the 3D printer on its own to avoid any fire hazards, look elsewhere.
Also, the button got stuck at one point. If you loosen the 3 screws, it fixes itself.

Connected to the Sonoff Zigbee Bridge that I have immediately without any problem. I have had it for about a week and so far it works flawlessly without any disconnections!
