I personally saw him in Shul on Shabbos. He wears Rambam strings 7-8-11-13. Doesn’t feel there’s anything wrong with Radzyn or Murex Tzitzis since the color reminder is what’s important. – Rafi Hecht
From Yeshivat Lev HaTorah:
“Rav Machlis received Semicha from Yeshivat Torah v’Daat and has been teaching for 25 years. He powerfully personifies chesed, dedicating his life to promoting love for all Jews and modeling a profound respect for every human being. He and his family host around 100 guests in their home each Shabbat, exposing his guests to the beauty of Torah and a vision of true Jewish unity.”
