Do not buy from this site
I purchased a pair of Wiley WX polarised in February of 2015 for 211 SGD by November most of lens coating has peeled off. I therefore claimed under the 12 month warranty. I was informed (after sending numerous pictures) that I had a valid claim and that Smartbuy glasses would order new lenses. But it would take three to four months. Perturbed I waited the 3 to 4 months. Some 9 months later still nothing. I have bent over backwards to accommodate Smartbuy having sent probably over 10 emails but they just do not care. Save yourselves some time and order via a proper shop or online site that honour their terms and conditions.
