"Know from BJJ Globetrotters camps"

"Met him in Dresden and had some epic rolls with him at BJJ Focus Camps Leglock Extravaganza. Have not rolled with him since he was a purple, but trust the documentation."

"Legit profile congrats on the black"

"Horst's skills are attested to me by my friend and student Andre Prins, whose judgment in this area I trust implicitly."

"What an amazing promotion, lucky to have been a small part of it. And already missing you brother."

"I'm not surprised at all Horst is a black belt now, he's technically sound, strong and a fun guy to hang out with and train. Congrats!"

"Bluebelt von Ulf, lange am Ball und jetzt der einzige BB des travelling Council, den ich kenne: Congrats!!!"

"Horst is my training partner. I was also present for his promotion to black belt. Very well deserved and he is a great teacher."

"Great documentation"

"Nice pictures of promotion. Congratulations on the BB 💪 "
