If the lid followed the line of the body it would look a lot better for me. A bit 'flying saucer' looking which is fine if that is what you want. Just a thought, if that centre piece (the dark part, was an insert that came out seperately, it would have that 'hidden secret' factor as well. As far as I can see the quality is fie, just the design which is the hard part as you will never please everyone with that.
