Big Clive, who makes these videos does some brilliant tear-downs. I recommend watching his other videos.
Big Clive is _the_ channel for teardowns of everyday electronic stuff. I am actually not that interested in this kind of stuff but somehow I still watch most of his videos. If you are into more... entertaining teardowns you should have a look at AvE. Even if you don't like it you will still learn some useful canadian terms ;) (edit: just to make it clear, AvE is actually very knowledgable. His "boltr" teardown series…
His style is... unique. I think it's great but I'm sure it's not for everyone.
