Magic Mouse 2 Casing Is "Loose"

My new MM2 works just fine, but it seems the glass part is some kind of "loose". You can wobble the glas part when holding the mouse in hands. Makes me feel as if it doesn’t fully fit its aluminum case and apart from that it makes some disturbing click noises, just by simply touching it (the double touch zoom gesture sounds not very promising in my opinion).

Are all these new mouses build that way, or is it just mine? Really gives me the feel of bad quality.
