I ordered this to use with my knockoff brand label printer. Its modeled after the brother P-Touch label printer but apparently has some minor differences in the label cartridge slot. In order to fit this cartridge in my printer, I had to cut some plastic off from the cartridge to get it to fit but once everything was in place, I was able to print laminated labels with good results.I won't hold this fitment issue against them too much but based on the modifications I had to make, there is no reason why the manufacturer of this label printer cartridge couldn't include a couple extra cutouts to fit a wider range of printers. Besides a couple extra holes in the cartridge, there are no other differences and it works well in my label printer.Overall, its a good label cartridge. It would have been nice if some extra slots in the cartridge were included to expand printer compatibility but I'm sure it fits the genuine Brother P-Touch printers. Consider me a satisfied customer, but I will not be purchasing again since this cartridge does not match my needs.
