In the past I have wasted money on items that looked good in photos but felt cheap in real life. Nose pads that are too hard leave marks and feel uncomfortable on the skin. That is why I sometimes leave comments myself when I test a new shop or product.

If anyone is interested in real user experiences, I sometimes write short notes about the shops I test.

Reading comments with real body photos is one of the best ways to check sizing. People who share height and weight information make it easier to choose the right size. I think this is one of the few real advantages we have compared to shopping blindly. I prefer simple designs that do not depend only on heavy filters in the pictures. Trendy pieces are fun, but I only buy them when the price is reasonable. Over the last months I noticed that some of my favorite items are not the most expensive ones. If many different people say the same thing about a product, it is worth paying attention. Reviews that mention long term use are more valuable than comments written on day one.

Hope this helps someone.
