If tracking never updates for weeks, I start to worry about the order. I have learned to avoid items that look extremely different in every product photo. For things that I use every day, I prefer to pay a bit more if the quality is stable.
If anyone is interested in real user experiences, I sometimes write short notes about the shops I test.

I think this is one of the few real advantages we have compared to shopping blindly. I like when they mention whether the fabric has stretch or not, that detail matters a lot. Some charts are very generic and do not match real measurements at all. This is why I like reading and posting on forums and community websites. Metal can feel more premium, but acetate can be more comfortable for long wear. I think sharing honest feedback helps other buyers avoid the same mistakes. Everyone has different expectations, but real photos and detailed comments are useful for everyone. When it comes to eyewear, the small details really matter over time.
Hope this helps someone.
