I had a set of Zondas, they are great wheels for the money.
2 problems though.
I snapped quite a few spokes (85kg), and because of the spoke design, losing one spoke meant that the wheel wouldn’t spin in the frame. Spokes are unique and quite expensive.
I destroyed the rims in 3 days in the Alps, it was wet which didn’t help, but they wore away at an alarming rate. Replacement rims were almost the same price as a new set of wheels.
Currently on RS81, which seem to be holding up better.
