Review on myCartridge PC501 Ribbon: Compatible with Brother FAX 575 Printers (Pack of 4) - Ultimate Printing Solutions! by Mike Meyers

***Update below!***. So far so good with these! My boss was suspicious and didn't think they would fit or work properly so we bet, glad I won! Thanks for a great product! Update: We received these fax cartridges today after probably ordering these 4x, no problem, they actually lasted longer than any we bought in the store. today, however, was a different story. One of the cartridges was completely broken and would not fit into our machine. The second got stuck when printing and the whole fax machine shook a lot! I think what happened was the tape was sticky or something because once we got the paper jam out of the machine we had to peel the tape off our paper. To be too good to be true?
