“Kudos to whomever is in charge of packing. The box arrived crushed in at one corner, yet the glasses survived. No flaws whatsoever. The 3.0 was perfect. The glasses themselves, while a tad heavy are awesomely crafted. My only grievance is that they don't stay put on my nose...sliding down & having to push them back up for the time that I wear them. Nothing to do with sweat, just not a great fit for my nose. Otherwise....a fabulous product.”
