I purchased two sets of these a while ago, 2019 I believe.  They're fantastic - I used them primarily for gravel, then recently as a road training wheelset (they're very similar dimensions to Zipp 303 Firecrests but hooked) and now CX.  Only maintenance I've ever done is regreased the freehub pawls on occasion.  Finally knocked the front wheel out of true after a gnarly cx crash, but it wasn't noticeable until I put in in my stand afterwards.  The second set is my wife's and she loves them - gravel only.
Highly recommended.  I believe GCN did a video on these where they tried to destroy them and they took quite a beating.  Only negative IMO is the `tubeless ready - adventure ready` text on the rims, but this is purely cosmetic.  You should buy them.
