Paying $65.00 to $70.00 for an undersized (.75kg not 1kg) roll of filament is unacceptable. Having only 5 choices of filament color (red, white, orange, black and gray) is unacceptable. Having a RFID chip inserted into each roll that incorrectly tracks the amount of filament on the roll so that you end up throwing away a significant amount of filament because the MakerBot method printer will not allow it to be printed is, again... UNACCEPTABLE!
