Registered here specifically to post review of Reprap.cn (same people also on reprapmall.com, Hoyi Sunway on Aliexpress etc.).
While prices look low, they are because with the non-existent support, incomplete kits they sent and the denial of documentation for an open source product, they can't get any more.
Save your money, look elsewhere.
Will post specifics of the horror I have gone through ( waited patiently for 2 months trying every option to get heard) if anyone interested in the rants.
