As described. I have had no problems so far. Its only flaw is that, even when it is switched off, a small current passes through. I realized this when I plugged in some lights (like Christmas lights) and, even though it was off and nighttime – with no light in the room –, the lights had a very faint glow. So current does pass through.

If you don't have good wifi, don't get them. Where other devices have a good signal, these don't have good or any signal at all and they disconnect. I have 4 with tasmota for use only close to the router

It's good and provides information about consumption, but I give it four stars because it doesn't catch the wifi well and can often disconnect.

It works perfectly without disconnections. I have programmed it for the Christmas lights on the balcony to turn on and off with a timer!

Very good choice, easy menu. I have a general app for such devices (hombli) and it found it immediately. When it is on, it has a light that I assume is there for safety to let you know when it is activated even when there is no device plugged in. Personally, the light doesn't bother me even while sleeping. It also has a button to turn it on/off on the spot without the app. It is definitely worth the money.

It works steadily and without disconnections, unlike the SP112 which often disconnected. Also, their size is much more convenient. I highly recommend them.

Very good and cheap socket. Discreet in size, it doesn't even show. Easy connection and nice consumption history.
Something that is not mentioned much and bothered me is that when the socket is "on", it has a permanent red LED light, to show that it is working.
For me, this is discouraging because I wanted to put them in air conditioners that have the socket high on the wall and in a nightstand next to the bed. As a result, I had permanently lit red LEDs in very visible places on the walls from the air conditioners, and in the bedroom where I want complete darkness at night, the LED was like a flashlight.
It does its job but it is not discreet at all despite its size. In the photo, the LED is more intense than in reality, but still a terrible lack of being able to deactivate the LED.

Excellent smart plug which I have found to be reliable, easy to set up (I used Tuya Smart) and gives nice features for the good price - like a reading of how much electricity has been used, time schedules for automatic on-off operation, etc. I am pleased with the product.

4 stars only because the photo is misleading... it implies that the LED changes color according to consumption, but that is not the case. Other than that, it is like all the other sockets that work through Tuya, with the only advantage being its smaller size.

Very good choice for converting simple devices into smart ones with remote management, consumption measurement, and programming functionality.

Good construction and the GOSUND application is very good and easy to use.
I have installed one socket in my house in Athens and two others in my vacation home where I manage heaters and lights.

It's worth it. The consumption indicator is very convenient. And it works with a heater on top of it. It really is worth it, also because of the Watts

I bought this specific socket for power consumption below 500 watts and it was the first smart one I bought. I was disappointed with the disconnections with my router, which were annoying and made the product useless. Within 48 hours, it is certain that it will disconnect and not reconnect unless you unplug it and plug it back in. I bought the TP-LINK one instead and I was saved. It was also slightly more affordable than this one... No disconnections with TP-LINK!!!!

Stable connection, high accuracy, deviation below 1 watt compared to nominal operation of various devices.
The only "negative" is that it retains the last measured value, so if you open it and have a connected device that is turned off, it will appear to consume watts and the only way to understand that the device is off is to see that the daily kilowatt hours do not increase.

Discreet, as it is not bulky. I have it on a T and it is constantly on without protruding.
The issue I have noticed is with the application. After 1 - 2 updates of the app, I have an annoying problem. When I go into programming for on & off, all commands need to be done twice. Meaning, I set it to turn on at a specific time and day and I press save, it goes back to the table with the programs I have already given and it is not included. The second time I set it, it appears.
The same thing happens when (again in programming) I activate a program that I had turned off. I have to press ON twice.
I use it to warm up my coffee maker.

Update: 16/03/22 just received an update and the bug has been fixed.
I wrote all this for nothing

I suspect poor WiFi reception. In areas where a TP-LINK HS100 smart plug "sees" WiFi, the Gosund does not find a network and remains offline. It seems to struggle with walls. In the network diagnostics, it showed a weak 2.4 GHz WiFi signal 3-4 meters away from the router. On the plus side, its small size doesn't take up space on the power strip and doesn't interfere with the wall outlets.

EDIT 10/12/2023
I have TP-LINK and Coolseer smart plugs and cameras from Tapo, XIAOMI, and others. No device disconnects from the Xiaomi AX3200 router except for the Gosund SP111, which shows a weak signal just a few meters away and doesn't even connect in another room. So, I repeat, it has poor WiFi reception.

Connected with tuya smart and works great, keeps consumption history and if the power goes out, it retains the last state for when it comes back.

It worked well until I decided to measure another device. So, I reset the meter and tried factory reset & hard reset several times, but it didn't reset all the kWh, it kept 5 kWh. Okay, let's overlook that. I put the device to work and it showed the current measurement, but when it went on standby, the device continued to show consumption without anything being connected, that is, through the gosund application. What can I say, maybe I got a defective product. On the positive side, it has a very small discreet size. I also downloaded the blitzwolf application called setara, and now it shows me live measurement, but it didn't reset the total measurement.

VFM the socket, I bought two and I have installed them on radiators connected in parallel with Amazon Alexa and a digital room thermostat. The measurements in KWh are equally very good.
