I find that what people use over and over is a pretty good assurance that the product or service really does deliver. Sometimes it doesn’t work for me but I always learn something.
If you want to find out what people carry and use all the time do this simple exercise; search google images with these words “every day carry” The array of “gear” that people carry in their pockets and on keyrings etc. is astounding.
Often this will lead you to some great equipment that you can add to your own kit.
