It's really an invaluable addition to a 3D printer. "Safely" allows filament runout, allowing efficient and complete use of filament spools without any splicing.I've even fixed a tangled spool mid-print one time by simply cutting the filament, fixing the issue, allowing the filament to run out and continuing the print.The cons: the unit was EXTREMELY noisy when I received it; it took hours of troubleshooting and finishing on printed components that should have been done before the unit shipped. Only opening the unit, filing, and removing stringing left in the assembly from the printing process finally eliminated the extremely loud clicking noises coming from the unit during printing.
