For product: Size: Fits me perfectly, would say I have an average head size. (Many a melon head, the glasses do not fit). The lenses also have an usual size (appropriations for pilot goggles)
Processing: very good for the money, not yet have long-term experience.
Glasses: Mirrored version does not allow to see the eyes, In Black you can easily see, In yellow you can very easily eyes, etc.. So everything is as it should be.
Conclusion: For the money you get here or in stores probably no better. It makes sense if one is equal to 2 or 3 orders, to save postage (in case of damage, etc. tell speakers of personal and good service therefore no risk) If you do not have larger than average head, the glasses should fit well and the lenses are large. Look good and are well crafted.
