I noticed that the hinges were quite stiff out of the box but I didn't pay much attention, just a good precise fit and decent signal quality. Not so. Opening and closing began unscrewing the left shackle (plastic) from the hinge (metal). Then the last fastener tightened the loop so much that the shackle could not withstand it and broke off the loop. This was only the case after 2-3 weeks of half-daily use. I wouldn't pay 50€ more for it. Otherwise, drooping lenses (polarized) are definitely great for being in the water and out in the bright sun. I found I had to take them off while driving as it was overcast because they are so dark. But the lenses are great for what they're designed for - watersports.
