I'm not sure his test is the end all and be all for phone tests. I've had 2 of his "wall of shame" devices (well I guess 3 now that I have a KEYone), and I loved my Nexus 6P. Although I WILL admit I DID have durability issues with my Nexbit Robin, BUT on the plus, Nextbit stood by their product and quickly replaced my device that had developed micro cracks over time.
My KEYone appears to be VERY solidly built, and I have no plans to abuse it the way Zack does in his videos. Additionally OTHER than the screen issue he noted the KEYone actually fared quite well in the other parts of his tests. I'm confident that if I DO have any issues with my KEYone that BlackBerry Mobile (TCL) will stand behind their product also and replace it!
So I guess my bottonline is IF you really like the U11, I say get it! HTC has your back! Don't give JerryRigEverything THAT much credit. Yea the videos are fun to watch, but they ain't everything!
