Fast delivery. Began purchasing & using over year ago after purchasing Brothers MFC5460-CN. Great price, good quality, initially good value using older, plain-generic looking packaged containers. Newer, slicker, all black containers give out much quicker. They don't seem to have as much ink--aren't full or only hold small amount of ink. Because they are now completely blacked-out, can't see what's inside them/ink levels through the black containers. Ink and levels were visible in previous packaging...could see that they were completely full. One got much more printing when using them. The all-black containers just don't do that. They empty very quickly so must be replaced more frequently; therefore, haven't proved to be such a great deal/value. I'm gonna order once more in hopes that I will receive the original older packaged cartridges. If not, I'm done.
