Came apart in the first week. I returned it. Vendor very quickly supplied return postage and refunded the cost. I had hoped these would have been John Lennonish enuf to proudly wear them. They are rather bulky and the side adjusters add to this chunkiness. The gel in the lenses tended to separate and blur vision. Perhaps I did not know how to use them properly but there was no instruction set included so I was on my own. If you want something off the wall looking for your next rock festival then go for these but for everyday use I would look for another option.
