You know what they say about opinions, well here comes one.
I found myself fast forwarding until I actual could see some circuit board. The beginning of this video was "as boring as bat shit". I love tear down video's, they rock. This one, not so much. I'll admit it got better toward the end.
Find some more test gear to tear apart, something people might actually own or can relate to.
Things not to tear apart: Cell phones, calculators, remote controls, etc. If it doesn't have a power supply inside..it might end up just being boring. Survey the populous, find out what kinds of stuff people want to see.
Hey, just my two cents.
