Dubman …Bontrager are decent, not flashy but solid kit. They used to spec them on Cotic’s etc., sounds a decent deal.
Personally not risked carbon rims on my MTB as being 17+ stone I’d be concerned about bad impacts compromising them. Have them on my roadie though (not expensive ones, Chinese factory) and they are an awesome upgrade. Rotating weight is the biggest weight saving on a bike, you really feel the difference.
