Buy some prefer another plug covers, this one can confidently throw in the trash. The adhesive strip is no better than a piece of adhesive tape (Tixo). The Steckdosenschutz holds not in the socket. From the first use, when I pulled the vacuum cleaner plug from the socket, the plug covers came out from the outlet. It did not even ONCE! Total to forget. And that was not only a Steckdosenschutz so, but in all that I have attached by reer. Not a single thought even a single time. All came mitraus when pulling the plug. I had in my old apartment outlet protectors that clung to 2 years and NEVER came mitraus also only once the outlet protection. I even entfert the old out of the apartment and purely stuck again in the new apartment and they have kept super again. Unfortunately, that are no longer available. This socket protectors of reer I find even dangerous, because if you are not careful, then the outlet's unprotected and relying on it so that it is protected and can play the child safely in his room. Since I would still usefully find no outlet protection to install, because then at least you know that you have to keep your child always in mind. I do not understand why not just ordinary tape has been used here, in the safety of babies and young children but should not be saved. Better they cost one euro more and are for sure as it then something happens. Do not understand how the manufacturer can be so thoughtless and careless here, just outrageous this product then sell as safe. This product is just plain rubbish.
