If tracking never updates for weeks, I start to worry about the order. Even big and famous brands sometimes send generic replies that are not very helpful. A product that still looks good after a few months is more impressive than something only good on arrival. Now I try to read as many real user reviews as possible before I buy anything.
If anyone is interested in real user experiences, I sometimes write short notes about the shops I test.

That is why I sometimes leave comments myself when I test a new shop or product. Some charts are very generic and do not match real measurements at all. If buyers say the item runs small or large, I always adjust my choice accordingly. I think this is one of the few real advantages we have compared to shopping blindly. Over the last months I noticed that some of my favorite items are not the most expensive ones. In the past I have wasted money on items that looked good in photos but felt cheap in real life. Having a tracking number that works on common sites is very convenient.
Maybe this is useful for someone.
