Does anyone actually like TechRax?

This guy just ruins phones for no reason. Maybe seeing how long a phone would last in water would be interesting, but in a video this guy posted, he just slaps the phone onto a magnet. Why would anyone like this / be amazed that the phone doesn't turn on in the end?

Here's the iPhone vs magnet video: https://www.youtube.com/watch?v=qGAbuTrm_bI
