He's a big goofy dude, and he's the first to admit it - you gotta give him that, and I can respect that. And he was one of the first guys out there doing actual vids (instead of just shooting his mouth off on some forum) about what he does, why he does it, and what works or doesn't work. Plus he does have 20 years of military service under his belt (can't say anything bad about that).
He has done a ton of actual outdoor testing of gear for one primary purpose - to provide viewers with data points (unlike many of these wannabe's on YT who do "reviews" but you NEVER see them outside actually using the products they are reviewing - that is lame). What you do with the data points Nutn' provides is up to you.
I think most people who don't like him haven't watched enough to know why they don't like him. The same paradox applies to Rush Limbaugh - most people who tell you they hate him have NEVER even listed to his show. My bottom line is this: when it comes to any YouTuber - if they provide information from a first-hand demonstration about something I'm interested in learning about, then I'll check out their vids. Then, I decide for MYSELF if the information is useful to ME. That's what YT is supposed to be for anyway. Well, that and stupid cat vids... Hehehe....
Btw, I'm not a fan-boy, but I can tell you one thing for sure... "The Owl is on the Shed."
