Koxx-One Karbon Koncept

I came across a guy riding a Koxx-One Karbon Koncept earlier today. I didn’t get a chance to talk with him about it though.
When I returned home I looked it up on here and there are a couple of discussion from a few years ago where people are saying that while it looks awesome a carbon frame is subject to massive failure.
I am wondering if anyone has had a Karbon Koncept fail. Any pictures or stories of a broken frame? Also, if your frame broke would you buy one again?
