Review on RETCH Compatible Drum Unit DR221CL Replacement for Brother DR221 DR-221CL Printer - HL-3180CDW HL-3140CW HL-3170CDW MFC-9130CW MFC-9330CDW MFC-9340CDW - Black Cyan Magenta Yellow by Jerry Eintertainment

My printer keeps telling me that my drums need to be replaced and all my print jobs have been horrible since these drums were installed. the number of traffic jams has increased and much more. My husband built all of our computers, worked as a copier and printer technician, and installed them. He has repeatedly worked with these drums on the printer in order to get them to work. We thought we might save some money by buying it, but it ends up costing more because of wasted print jobs and having to buy other drums anyway.
