So they look nice and, at first glance, fully correspond to the declared. However, some adapters may not fit all outlets. For example, the same lamp cord that fits into the adapter on one side will not fit on the other. This indicates a manufacturing issue as the same lamp cord will fit some but not all connectors. Not sure I'll be back as I only needed 2 of the 3 connectors for my application; The only problem is concern that a manufacturing defect affecting the plugs could indicate an increased risk of electrocution.
