Everyone has their own way of telling their story and I see nothing at all wrong with including as much detail as someone choses to share. Actually, I like to know what folks are using in such situations. It's useful information. A generic description may appeal to you, but may not to others who prefer details. Let's not discourage folks from sharing in whatever way they want. He doesn't appear to be selling these flashlights, so it's a reasonable way to tell his story.
