Chinese MGN rails. Should I use them?

Just got a quote from hongyi automation for a kit with 300, 650, and 850 profile rails and 3 ball screws. For hgr20 rails it was 376usd and hgr15 rails was 355usd. They confirmed that are not hiwin rails. Has anyone used the hgr rails from this place? Would you recommend them?

You will have to risk it. The fact that the other rails from them were great and that as seen on pictures they have bothered to laser mark the blocks are very encouraging. I would say the chance for them to be great rails is more than 90%.
