Query: lightweight tin top

I was quite surprised at the very thin sheet metal top. i expected more from Peugeot, especially at this price. i'm afraid this will dent if i just knock it over on the table. I guess I should have known better than to expect a solid metal topper, but that is what it looks like, and i bought it to get something 'substantial' - not a thin, hollow sheet metal bulb. waste of money. it grinds OK, though.
