I respect any the effort that someone puts to help someone. Maybe I am old fashion but any video review is not useful to me even currently a very popular way for "how-to" guide. I have a feeling that this is primarily a waste of my time watching how someone opens the package and showing some of the most ordinary things.
I suggest you add textual content in your reviews for non-lazy people.
I prefer to read as well, but I believe the main reason why we have so many video reviews is that it is easier to make money from videos.
Sometimes ledger/trezor/etc send you free products if you promise to make a video about them as well, unboxing and stuff.
