Very good protective case! Easy to use (and you can easily put it on and take it off!!) It's worth its money! The key is not necessary. I recommend... I would like it to be completely white so that it doesn't catch the child's eye.

I had recently purchased protectors in a package that also included protectors for sockets from a well-known e-shop, they turned out to be a joke, it didn't take much effort for the baby to remove them, they almost came off on their own. And searching, I found these here. They are easy to install and definitely provide more safety, as the baby cannot approach them at all since they are essentially inserted, and it loses interest immediately. The only problem might be, as other users have mentioned, what happens if the key is lost, which we keep as a precious item, but I believe that something can be done even in this case. I am ready, however, to purchase a second package for my grandparents' house that we visit from time to time, and the sockets always remain a favorite type of entertainment.

They are not crazy quality. After some time and use, one broke. But they do what they say. And they are worth their money. And they don't necessarily need the key. You can also unplug it with the plug of the socket. Not as easily though. But in need

Once you lose the little key, forget it, it will stay there forever. (Figure of speech). However, for protection, 5 stars. I wish it came in another color.

They do their job well, cover the socket properly, and the child cannot remove it without the key because basically there is nowhere to hold it. However, I don't give it 5 stars because the process of putting it on and taking it off with the key is a bit of a hassle, not to mention that if you can't find it, it drives you crazy. The house was well covered with the 6 pieces.

It is good, you just need to have the patience to remove the key if you want to bring it. If you don't, you should get another one

Perfect price, flawless application, the baby cannot take them off, neither can I, without the little key. Safety...

It does a good job and it's also cheap!
The only maybe observation is that in order to use the socket, you have to insert the key to pull the safety out...
maybe in practical terms, those sockets that go inside and you twist an object to secure them would be more convenient... so that they are safe for the child and you can use the socket...

Perfect! Very beautiful and secure. You can easily unlock them with the key. We have ordered many for our country house and also for grandma and grandpa's house.
