I read all the reviews and was quite confused whether to buy this or not, as most of the reviews of this sunglass are negative. But I bought this one and can say formly thst its not duplicate or fake, its original fasttrack. This same sunglass with same product serial number is listed in Titan Eye Plus website. In a very low price it gives a good gradient look. Absolutely happy with the look, quality of the glass, now in long run can judge whether the glass gets scratches or not
