It broke within 2 months and made some 'strange' noises (as if it didn't make good contact, which is not true). Because of this, the air conditioner would do some strange things (probably related to the voltage it was receiving), like completely shutting off and then turning back on after a while. Luckily, nothing happened to the air conditioner and of course, as soon as it stopped working, I threw it away and bought one from another company, and since then everything has been working perfectly.

As mentioned earlier, its main problem is that the plugs are difficult to insert into the sockets, even after a long period of use.
If you want to have the plugs permanently on, go for it. If you want to constantly plug and unplug them, I would recommend choosing another one.

After less than 3 months, while simply unplugging a device that was not turned on (kettle), it blew the relay and gave up the ghost.

I put it to protect the TV more. I believe it's fine.. It's just a little difficult to plug something into it.. Maybe I fell into the case.
