The LG V30 teardown is pretty impressive too. I watched it first, a couple weeks ago, so the iPhoneX teardown didn't do much for me. If I had watched them in a different order, maybe I'd find the iPhone one more impressive.

Though most impressive ever for me was a Panasonic cassette player (walkman style) in the 90's. The thing was barely larger than a cassette itself. My young mind was blown out.
