Word-of-mouth, popularity, familiarity and availability are the biggest factors for using some products; and of course how well it works. A lot of times products find us. I usually start using an app or product, until I find something that is better. OP has a long list of very specific list requirements. When I have specific requirements, it is usually about ingredients in food items, or things like 100% cotton shirts; and it is rather a short list. How do I find them -- it is usually hard.
