The lenses are optically really a looker, but of 12 pieces after 3 months now 3 broken in very rare use (2 of which only 2 times). All 3 jumped up on the edge or broken and leaking come out of the dishwasher (2 different Spühlen). A glass can indeed times get broken, but equal to 3 of 12 then leave but certain doubts about the quality and processing of flare.
