A number of items in the description including the cloud portion, the proprietary filament cartridges, nozzles as part of the cartridge all have similarities to a poorly engineered product known as Cube 3 from the not too distant past. Until the mechanical problems began to appear at the local library's Cube3 printer, I thought it was a wonderful printer. Nope. 300 g of filament for US$50! Who pays US$150 or more for PLA?

Run away.
