It does exactly what it says. The time delay is very important. I bought five, two refrigerators, two air conditioners, and one freezer.

I agree that it does what it says, and it is a must for refrigerators and air conditioners, especially with the 90-second time delay it has in case of momentary power outages, which can be disastrous for compressors. Just be careful, the delay is fixed at 90 seconds and not adjustable as the description says.

I have had it for 4 months so far. It works normally. I have put one on the air-conditioner and the other on the fridge. During the power outages that have occurred, it works correctly. The delay time it has is very positive. I recommend it!!

very good for protecting refrigerator, air conditioner, washing machine, etc.
The 90sec delay is just right for this kind of device! Its price is fair, even from China similar devices with a 5-minute power cut cost the same if not more expensive...

It seems to work properly, the 90-second function it has after a power outage is very good, I have it together with a voltage stabilizer and the stabilizer seems to have calmed down a bit since I connected it, meaning it does its job, I hope it lasts

It was plugged into the washing machine socket and since then we were getting electric shocks from the sink, which means it wasn't properly grounded!!

I'm not an expert but since I removed it from the washing machine it stopped when I plugged it into the socket with the computers! That's all

Installed on a pressure machine for a water tank, because frequent power outages burned the pressure board three times. Over time, it will show its durability. However, upon installation, there was an immediate green indication that it has stable power.

Simply perfect! Very good build quality and it really helps in terms of protection, in case of overvoltage but also when the power comes and goes again, this delay before activation can prove to be lifesaving

This particular socket goes out of order when the voltage drops and does not come back. I stopped using it. I used it on the TV and it would turn off as soon as the voltage dropped. I would not recommend it.

Honestly, I didn't find any flaws. After about 3 or 4 years of continuous use in the refrigerator and television, they are still working, and only this year, the one I had placed on the computer and multifunction device broke after a storm without any damage to the computer system, which it protected excellently. Everything works 24 hours a day.

A television and a refrigerator that I have put inside saved it when the electricity company was sending that there would be a voltage for two days

Very good vfm choice for protecting devices with a compressor (refrigerator, air conditioner) from under-voltage and over-voltage as well as dips within 3 minutes. It features a microcontroller and comparator. The over-voltage spike protection is basic (one varistor). If it had better over-voltage protection with 3 varistors, it would be the ultimate choice even if it had a higher cost (Shupco used to make it but stopped). A preferable choice over bulky voltage stabilizers with high self-consumption (of course, they have a different operating principle)

In a duration of 7 months, it has withstood repeated and frequent power outages, gradually restoring power to the connected devices, without either them or the product showing any problems (at least so far).

For light use. It does not support dishwashers, washing machines, refrigerators, or cooking hobs. On the plus side, it has a delay time for repeated quick power outages, especially before a permanent network failure or during the restoration from a network failure

It's worth the money and then some. It stabilizes the power after outages from the electricity company at home to the outlets, smoothly without any problems. Place it where there are electrical appliances in your home.

4 were purchased. They were placed in sockets with sensitive devices. 1 month of using them, they did not show any power instability. I hope that when needed, they will respond correctly.

Very good, I live in an area where unfortunately the voltage often drops during this season and we have power outages. It worked in all situations! The devices will be saved!

I bought two devices and none of them were sealed!
Every time it is plugged in, it takes about a minute and a half to stop the green light from flashing (indicating good operation) and then remains steadily on.
It is more "loose" than it should be in both sockets and does not put any strain on the socket it is placed in, whether on top or underneath.
I also tried it with a powerline I have at home to transfer internet through the electrical line, but the speed on a 100Mbps line dropped to 50-60 (at least 30Mbps loss)! I tried it in another socket about two meters away and got the same result. Therefore, THE DEVICE CAUSES A LOSS OF INTERNET SPEED BY 1/3 when transmitted through the electrical network! Unacceptable.
The logic of the device is "to foresee and prevent is better than to cure", so I agree. Time, as the only judge, will show if it will protect our devices from surges, sudden outages, and noise, as it promises.

Excellent and very high quality something that is not so clear from the photos. So far I had 3 power outages and it worked exactly as it should. The 1.5 minute delay works correctly and its cancel button, too!

I bought 2 and after some tests, I bought another 2. I have connected all the electrical devices in my house. I have frequent power outages from the power company. 3 times I have noticed that after an outage, it has automatically restored itself after a few seconds when the power comes back, so it covers my needs.

A very good product that will protect devices from any power surge or power outage.....I highly recommend it!!!! Best value!!!

I bought 2 to connect my TV and refrigerator. The power column of the electricity company is right outside my house, a detached house in a village, so I have a fear of power surges. It has responded immediately in 2 instances of power outage. It comes back on its own after a minute or so, so it covers me. The refrigerator makes less noise after I connected it.

It has not been necessary to operate, but it appears to be of good quality. If I need to protect any of the devices I put it on, I will come back in case there is a problem...

UPDATE after 3 years of daily-permanent use. It continues to work without any malfunction both in the refrigerator and in the air purifier. It still hasn't needed to "work" its protection.

I bought two.. it works very well on vacation. I'm satisfied anyway. I believe it's one of the best. Latest review: I put it in the fridge. I was away from home, there was a power outage and it burned out. The fridge didn't get power again, resulting in everything inside going bad. I came back and the place smelled. So if you are away from home, this can happen as I mentioned.

It does what it says, worth its money

It does what it promises.
Don't risk it with your devices, and get one for each device in your home that has some value.

Quality device with a voltage monitoring microprocessor and cutoff relay. This particular one has the advantage that in case of a large voltage difference, it disconnects the device from the network and reconnects it when the voltage returns to normal. Another major advantage is the time delay (1.5 minutes) in case of continuous micro-outages, which are destructive. Similar devices are continuously connected to the network, and in case of a large voltage difference, the internal fuse burns out to protect our device, which then needs to be replaced. It is understood that it is not intended for the protection of powerline network transfer devices, as these devices must be directly plugged in.
UPDATE 12/5/25. It continues to work just fine. Therefore, it is also reliable!

I had similar safety sockets from another company and I chose to get this one because I was interested in the light indicators it has. Right from the start, I saw the product in action when the power company momentarily cut and restored the power, and the socket supplied power with a delay, protecting my devices. Very good!
