Bests & Worsts Reviews from Amazon

This product will not fit into many standard outlets in Europe I have found, living in Europe. The simple reason is that the square plastic base below the prongs is a couple millimeters too wide and blocks the entry of the prongs into the socket. It won't work for example on a standard powercube and on my apartment standard wall outlet. I found some older outlets it works with but I'd say definitely go with a better design -- no one needs an adapter that cannot match all use cases in the region it was supposedly designed for.
