SA106 Tempered Real Glass Lens Mobster Flat Top Mens Rubberized Matte Sunglasses:  These arrived on time in a small box and the sunglasses were in a plastic bag inside - sparse packaging but sufficiently protected and I suppose economical to ship.  I have a rather large 7 3/4 hat size head and these fit and felt pretty nice, especially with the rubberized coating.  I have to note that in typical chinese manufacturing tradition the rubberized frames featured a contextually inappropriate &#34;hand polished frame&#34; label printed on one of the arms.  If there is in fact an employee somewhere in Southeast Asia polishing matte rubberized surfaces by hand I extend my apologies.  In any event the finish was what I expected and the lens size was exactly what I wanted, tall and wide.  The tint was even and the pictures on the site listing are representative of the actual color and darkness. The lenses are not what I would call good optical quality and there is some distortion but nothing unbearable at this price point.  What surprised me most, to the point of some concern, was how light they were.  I was expecting the &#34;real glass lenses&#34; to have a little more weight to them, weight I was willing to accept for the inherent hardness and scratch resistance of glass.  They are not as substantial as I had hoped.  The lenses do not fit particularly snugly in the frame, are a little creaky when handling the frame and to me they are indistinguishable from plastic.  None of these shortcomings should be entirely unexpected in a $10 pair of chinese sunglasses - particularly if they indeed proved to be decently scratch resistant.  Unfortunately the pair I received had an additional and ultimately critical problem.  The left lens had 3 subtle but very distracting vertical parallel creases or impressions running from top to bottom through the very center of the lens.  The exterior surface of the lens was smooth but inside were these lines.  At some angles they were difficult tosee, but when held up to a light source they became very apparent and were too stright and too uniform to be anything other than a feature of manufacturing.  The right lens did not have these lines so it's obviously not unavoidably inherent in the manufacturing of them - just a matter of poor quality control.  An email to the seller resulted in a prompt apology and a first class tracking number for a replacement pair.  This was a very pleasant surprise.  I will update this review when they arrive - hopefully the lens issue was just an anomaly and I can put a pair through a bit of wear and tear.  UPDATE August 5, 2015:  The second pair arrived today and had the exact same issue as the first - vertical impressions or creases inside the glass.  It's pretty baffling that they would send me another pair and not verify that the lenses don't suffer from the same problem that necessitated a replacement.  Quality control at the manufacturer and at distribution just isn't good enough to buy from this seller again despite what seems to be decent customer service.  Would I be thrilled with these $10 sunglasses if there weren't lines running through the lens? Probably not thrilled, but given I like the style, they fit nicely and they're comfortable, I would be quietly accepting.  At $10 they would be a solid 3 stars.  I think the whole &#34;real tempered glass&#34; aspect of these can be largely disregarded as a buying point, though time will tell if they hold up better under normal use.  Customer service regarding my issue was good but ultimately not enough to overcome a bad product.  I guess I have 2 pairs of $5 glasses to hopefully deflect debris while I mow and weedeat the lawn.
