I picked these up this spring. I built a ti gravel bike that I use for commuting also. I installed 700x33 Specialized Trigger tubeless tires and run them at 50psi. I upgraded from a 23mm WTB cross rim to this. The difference in weight and width was immediately noticeable. These wheel corner like they are on rails. I have put 800 miles on these so far, which is comprised of MUT, gravel roads and even a local trail that is flat and smooth. Flawless in every condition. On the MUT during a commute, the seams and heaves from heat are not even felt.
The only glitch I have had with these wheels so far is a broken spoke. Drive side rear let go last week at the nipple. Took it to my friend who does non-destructive inspections for the Air Force, and the x-ray showed the break was caused by torsional stressors. I am guessing a weakness in the spoke when threads were cut, then the building process did it in. No big deal to replace as the straight pull spokes go in and out very easy....except....nobody on the planet seems to carry DT revolution straightpull spokes! Even the 2014 catalog doesn't list them. If you are going to market a wheel as easy to repair by not using proprietary parts, don't use parts in a 2015 wheel that are obosolete!
That being said, these wheels are legit for what they are meant for. At 1500g, I would even venture to say cross would be no problem. These are the same rim as the BlackLabel mtb rim they use, so I think cross should be just fine.
