So I decided to flash out on a really good pair of sunglasses, taking a risk on buying an un-reviewed product (I'm 17 so £50 took a while to save up) and was very excited when they arrived. On opening I found they came with a good case but as soon as I saw them my heart sank. The first thing was my fault I guess as I thought the arms were going to be metal (they aren't by the way) but in this company's defense they didn't say they are. Anyway as soon as I picked the things up the nose piece fell off. It was only held in by a tiny screw which went less than a millimeter into the light and poorly formed plastic, scarred by the words "made in Taiwan". Changing the lenses involved bending the whole frame which did not look like it would hold up for more than about two changes. When I put them on I found the hinges creaked a lot. Always a mark of a cheap build and despite my having a small head the arms were far too tight. I sent them back and to the company's credit I did get a full refund no questions asked, I was just disappointed to have wasted time on such an awful product. If you're looking for a good pair of sunglasses with exchangeable lenses I would recommend saving your money and buying two or even three different pairs of "Rayzor" sunglasses (seriously, have a look at them now they are £12.50 each and 10 times the quality of this scam).
