The sleeves up and down a little sit tight. When unplugging the entire adapter may be unplugged when not holding him. The middle socket appears to be less tight, thus one can also find one-handed unplug.
Safety plug with thicker pins fit despite "violence" (and otherwise reports here in the reviews) not enter (tested with the safety plug my vacuum cleaner and my hairdryers).
With curved outlet covers (such as on the customer photos) does not exclude the couplers 3-way adapter flush with the socket, but there remains a gap at the edge of the socket.
For bulkier mobile power supplies, it could well be that no three power supplies fit side by side in the 3-way adapter. But as you can see on the customer photos, this adapter is suitable for many applications still a good choice.
Conclusion: recommendable
