Ignore any video where the guy has a stupid expression on his face in the thumbnail, as if he's trying to pretend to be confused that his picture is being taken. Those videos are guaranteed to be worthless and annoying.
Unboxing videos are essentially useless since they never test the tool, let alone actually use them. They stumble through opening a box like they're a 4 year old disassembling a rocket ship and say "this tool looks good, feels good in the hand, it's a great tool".
There's nobody in particular that I watch; mostly just searching for what I have interest in buying then sifting through the ****. Some suggestions already made here I will look for and try to watch some videos of interest though
Doing what TTC does and gaining the reputation where people don't just pick your stuff apart or are suspect to the results is tough. Plus youtube basically requires clickbait to succeed, it's a sad cycle. The guy from TTC is around on this forum and is a stand up dude, so that definitely has helped him, but he's got his formula down and enough followers that he's now a "known source" just like project farm...anyone new trying to break into it, takes a lot of effort and luck.
