The adapter is small, which is good for those tight areas where you may not have a lot of space on the outlet.
The prongs don’t fold which is a bit of a bummer for travel purposes, but given the size seems a hard feat.
The receptacle (USB-C) is situated on one edge instead of the middle. Personally believe this is advantageous as depending on how you swap it, the port could be high or low.
Overall on the sale price, I believe it’s a great value.
