The product is totally for the A .... The title is meant seriously. When I recently put the plug of our vacuum cleaner into a socket with this child protection, flew to meet me sparks and molten metal. The assurance was of course out also. Cause: The child protection mechanism is sealed by a small metal spring. This had slipped out of the guide and had during insertion of Steckes clamped between the poles -> Short !! Have it all these backups immediately removed and disposed of. Conclusion: Such a thing should not be placed on the market. Unbelievable how such a thing can be made.
