This adapter converts a standard household outlet on two sockets for devices with euro plug. So sometimes you can thus save the space for a larger socket Of course, only connecting cables or very narrow devices, such as small (USB) chargers fit side by side in the adapter. For a small devaluation leads to me that you can not plug all the way into the outlet adapter into a power strip, if next door lies a grounded plug. This could have been avoided by a different socket. The function is still given to me, and I for me personally no safety concerns, because the connector does not wobble and will never be moved anyway. I add a photo to the product photos to show the "problem" more precisely.
