I noticed that the silicone tubing that ships with the Chinese knockoffs is a lot thinner than the high grade silicone tubing. Combined with the fact that the cables are much thinner than my FS cables, it does lead to some uncomfortable pressure on sensitive areas in the rear.
If you are going to use a Chinese cable belt for long term wear, I'd probably recommend making sure the tubing has at least a 2 mm wall thickness.
