Bought a 3D printer and then everything was turned over to the Chinese seller. Really got screwed there. Missing parts, terrible documentation, and I can't leave a review on the 3DPrintersOnline Site, geee wonder why.....STAY AWAY. If you want to buy a 3D printer make sure it is shipped from the US or you may have to wait a month and a half for a machine that has bad and missing parts. ordered in the beginning of Feb and now its the beginning of Apr and I am still waiting on parts and trying to get this $400 paper weight running.
