CkitzeUS-2PC European to American Outlet Plug Adapter (2PCS)

So you can put an average european plug (let's say netherlands) and this coverts it to us no hassle?

Is the male end non-polarized (2 prongs of identical size)? And will the socket fit a polarized plug (one side larger than the other)?

Will a Type L fit in?

So a type c will fit in it?
