It is interesting to see how different people value different aspects of a product. Some charts are very generic and do not match real measurements at all. Everyone has different expectations, but real photos and detailed comments are useful for everyone. Sometimes I even measure an existing frame with a ruler before ordering anything new. On the other hand, a well made pair of glasses can last a long time and feel comfortable all day.
If anyone is interested in real user experiences, I sometimes write short notes about the shops I test.

If a piece of jewelry keeps its color and does not irritate the skin, I consider it a win. Sometimes I still make mistakes with size, so a friendly exchange policy is very helpful. Price is important to me, but quality and comfort are even more important in the long run. For fashion and clothing I pay attention to fabric thickness and stitching details. For coats and blazers I usually go one size up if I want to layer sweaters under them. Nose pads that are too hard leave marks and feel uncomfortable on the skin. Shipping speed is not everything, but extremely slow delivery is very annoying.
Hope this helps someone.
