I am really torn writing this review.  I bought a pair November 2014 and I would give them 5 stars hands down.  They were SUPER dark and just what I needed.  The construction seemed a bit cheaper & flimsy compared to some of my other sunglasses, but they were still durable enough for everyday use and did exactly what I needed them to do.  However, I cracked the lens recently--entirely my fault and opted to reorder a new pair (6 Aug 2015).  Put them on today and was shocked to find them barely dark and not fitting the 'hardcore black dark lens' as described.  I double-checked to make sure I ordered the right pair of replacement sunglasses; the brand and type matched exactly.  The only difference I found was the supply vendor--Nov 14: OverStockToyz, Aug 15: palebluedot, both fulfilled by Amazon and shipped Prime.<br /><br />I'm including 3 comparison pics.  In the first, you can see them side by side--original on the left, replacement on the right--and the right side is clearly a lighter tinted lens than the pair on the left.  The second photo shows an led flashlight shining through the replacement pair; the third photo uses the same led light on the original pair.  The replacement pair allow through substantially more light than the original pair.  Unless there were different batches and/or changes in the production process between my original order and the replacement order, I have no idea why they would be so different.  I'm in the process of returning the replacement pair and dropping the review to three stars.  So much for consistent product quality.
