Never been stung by tax on stuff from aliexpress.
I took delivery of my EVZeros last week. They are very very light. I'm going to try and weigh them this week, and generally compare them to a genuine pair. From a quick once over, the hinge is a bit stiffer, generally the finishing isn't as good and the lenses (as with all my fauxkleys) just don't seem quite as good. Not bad for ~$15 though.
