I have the gravel version of these on my Yoeleo G21 gravel frame. Was able to route all four cables fully internally too, but you will need to use their headset spacers regardless of how you route your own cables. Quality wise they are no better or worse than Winspace's integrated bars.
However, I would not think about giving Yoeleo a single dollar unless they are 100% transparent regarding what's in stock, lead-times, and fulfillment/delivery. They have become notorious for overpromising and underdelivering their fulfillment times.
