I have been using these for about 10 months. I have them setup tubeless on Velocity Dually rims and they setup great. The tread pattern is awesome for Michigan singletrack and rolls fast on hardpack desert (where I live now). I have used them for 100mi singletrack races, 125mi desert races, long bikepacking days on a variety of surfaces and they've worked well on all. I am noticing more wear here on the rock, but at this price, its almost worth it to plan on 2 sets a year.
