For more than 10 euros, we expect something else! I had read the other negative reviews but I wanted to make my own opinion (especially at the sight of pretty pictures of presentation). For 5 euros, I tell OK! but for more than 10 e NO! The glasses do not shake (though I tightened maximum). Color finishes do not talk! Leaving them for their "plastic pocket" painting had already skipped! In short ashamed to offer such a product at this price. They are not worth more than 5 euros !!!
