I had been unhappy with the cases that opticians give you to protect glasses, as they always seem to end up buckling and going out of shape, when in normal use. Usually when put in a pocket, you inevitably end up leaning or sitting on them, at some point - then they don't shut properly and become unfit for purpose. So I was looking for something stronger and found this item on Amazon, which looked like it would do the job and at a very reasonable price.
Having used this case for a few weeks now, it certainly looks like the answer and shows no signs of wear or damage. The case feels very solid, but is not too heavy. It feels much more sturdy that any of the cases given to me by opticians, which have buckled within a very short period of time. The closing mechanism is very strong and this also inspires confidence that this case will last. The brushed aluminium look of the item is quite "classic" and simple, with no logos or extraneous features - so it should be suitable for anybody and I would recommend this highly - especially at the current price on Amazon. A real "find".
