It was my third MLT-D105L I bought from123inK.ca. The first one lasted pretty long time before it started to give poor quality printing. For the second one lifetime was noticeably shorter (the cartridge started to squeak when printing). But taking in consideration price/ quality ratio I have bought one more. As far as 123Ink.com service (ordering, shipping) it is flawless.

Most of the cartridges I've bought have been fine, lasted a long time. One started acting weird after about a month and 123 replaced it at no charge. I've got one now that doesn't want to print on one side, just a fine line so I didn't notice at first. I think it's worth paying so much less than a manufacturers cartridge, but they're not 100% perfect.
