Picked up the Mixed 5D saddle recently. I have about 100 miles on it this week and I gotta say, this thing is awesome!
I don’t have any rides over 2 hours on it yet but I don’t see longer rides being a problem, although it is slightly firmer than I usually prefer, it’s shaped just about perfectly for my build and riding posture.

AI-Summary
Are cheap AliExpress saddles as good as top-tier brands?
The reviewer discusses the MIXED 5D saddle as one of three AliExpress saddles they use in their clinic. They describe it as extremely light and specifically recommend it for people with incredibly narrow pelvises and sitbone dimensions under 100mm. The saddle features a very flexible carbon shell, a massive rise at the rear, and tremendous clearance on the wings, making it good for riders who rotate their pelvis forward. However, they note the padding is not as good as 3D printed alternatives and that it is a bit delicate, having snapped on the inside edge from bearing weight on the front.
