1. It is very sensitive. Even minor entanglements cause it breaks down into its component parts. The assembly is then but again possible.
2. In our outlets, the protection can not be mounted. The screw with the socket is only possible if the existing screw the outlet is long enough. This is not the case in our sockets.
The product is therefore only suitable as a plug covers. A condition is "tinkering" craftsmanship and fun. The second condition is the proper outlet.
Despite two stars because the product idea is good (I like the vertical sliding mechanism better than the solution with the turn of the plug when plugging). An extra star because Amazon has kindly refund the purchase price.
