I bought a set in April for my Corratec hardtail/.
Within 40 miles the rear was returned as the freehub failed.
A few hundred miles later and I’ve had to send the rear back again. I suspected the freehub but was told that a pawl had broken.
Both wheels have needed truing/tensioning
The next time anything fails I’m sending the pair back as not fit for purpose and a refund.
My recommendation would be to avoid them like the proverbial plague
