I find his videos somewhat useful. If I am looking into buying a knife, gun, or piece of gear, his is not the only opinion that I take into consideration. I generally view these videos with specific questions in mind, and sort through the reviews, in hopes that my questions get addressed.
I will say one thing I have noticed in his videos-if there is a product, or type of gear that he doesn't like from the start and already has his mind made up about...he will make sure said item fails during his "nutinfancy clinic". Slamming that fiskars axe into rock laden dirt to chip up the blade is one example. The beating he put that Pocket Bushman through is another.
I have the Gerber Camp Axe by Fiskars, as well as the newer version of the Pocket Bushman, and both are fine products well worth their price-and perform as advertised I might add.
