Review on Ink Replacement DR730 HL L2370DWXL MFC L2750DWXL by Eric Trask

This drum unit is very noisy when in use, all the time. We replaced the original drum unit with this and immediately after use it started making a loud, constant buzz. At first we thought the printer was to blame for the noise. But after installing the drum unit in another printer, the same noise occurs. This was a two unit purchase and the second drum unit also has the same noisy attribute. We tested it on both of our printers. Needless to say I am very dissatisfied with this purchase.
