I wanted some sunglasses to wear while driving an open top car so went for these because of the toughened lenses and a headstrap to keep them in place. The glasses are well made and suit my face/look good but I find the yellow tint of the lenses difficult to get used to - yellowish clouds look strange. I haven't yet used them in strong sunshine so the tint might yet prove useful. Perhaps I have just become accustomed to blue or grey tints. One advantage of the yellow tint is that it seems to give a brighter image. The side shields are fairly easy to remove/replace and look as though they are durable. I suppose I had hoped for something a tad better overall given the price - but I don't usually buy 'fashion' or 'label' sunglasses, or anything else, so perhaps I have become unintentionally stylish and have paid the price for it. I found the side arms a bit tight against my temple but I do have a wide face/head. The rear half of the side arms are flexible and allow adjustment for comfort. The headstrap is quick and easy to adjust. Given my lack of experience of 'posh' sunglasses, and the seemingly good quality of the lenses, this product might be better value than I am currently allowing for. If the tint was more to my liking I would give them 4 stars - I would only give 5 stars to something exceptional. Product purchased 22/2/12.
