Uwell Caliburn defective products and bad support (Caliburn tenet koko)

[Kiwironic]

I have bought a caliburn tenet koko last year, and received it almost 4 months later (shipping delay) after 2 months it broke, only lights flashing, not charging, not vaping. You can see the videos:

I have contacted Caliburn and they sent a replacement unit which I have received today. It has the exact same issue:

Is it possible that the coil is breaking them? The coil is also original Caliburn coil used in an original pod. I bought so many coils and pods, but seems now that I have to wait for longer or switch to another device that is more reliable, I had so many Koko devices and they all break somehow.

Update:
After sending the information above and the videos clearly showing BOTH devices being defective. I have been denied service from UWELL, they sent me the following message:
