Caution. They do not push the bleeding edge, this makes for more reliable. The flip downside of this is they are often behind in some specifications, such as USB-PD car charger, etc. I am continually in conflict wanting more power in smaller size but then I want the item to work and work reliably.
Testing. I've not had an item fail on unboxing.
Customer centric focus. In the few occasions I got an issue, I got a quick and acceptable response.
Attention to design detail, well built and built to last. I have not had an item fail from old age (yet).
18 month warranty is extra peace of mind, particularly for higher cost items.
