I've owned a couple of sets for off-road use since 2018/2019. They ride nicely off-road. Agree with jfcb that they feel awkward on the road.
Mine requires YEARLY re-tensioning or the performance feels off. They are great if you have a mechanic to support you and you are an XC racer.
I've told myself they are worth it to me as someone who can easily do the tensioning, but honestly, they are a PITA to own.
