Just got mine yesterday finally. Btw, USPS tracking SUCKS and SUCKS more. Still no notification and tracking even when the product is delivered. Anyway, I am loving my pair. I so love how light they feel. You don't even feel you are wearing a glass and oh blocks the harmful blue light really well. I felt the difference immediately. Thanks Massdrop and thanks Gunnars for this awesome product. I might get a second pair as a reserve on the next drop.
