How it works: On the back of securing a small adhesive tape is attached. You pull off the protective foil and put the fuse into the socket. Finished! Will you now poke a plug, so you push it slightly to the backup and turns it around with the guide. Pulling the plug out again, the backup automatically reseals the holes. But I think everyone has seen anything like this: o)
I can understand the previously abgebenen negative ratings for product not quite. Some have complained that the parts do not keep well. If you clean the outlets previously sure it works better with the tape already glued on it. Part I even pressed without this tape into the socket and it works well. Of course, one is the fuse counter jumped, when you pull the vacuum cleaner cord! But if you touch the plug of an electrical appliance top and pulling out with feeling, even the backup stays where it should be - and without adhesive.
We have 20 pieces in the house. When we moved, we went only one when removing broken. But that was due less to the quality of the backup, but on my agility that would more gently can be; o) All other backups we have reused!
I am happy with the product and would buy it again.
