there were streaks of what looked like blue ink.  I pretreated the marks (2 separate ones about 10 inches long) with Dawn dishwashing liquid and a little diluted bleach and washed in machine.  They came out but I was a little freaked out when I saw them.

The pattern was stuck together. It looks like something was spilled on it.

At first OK, but after one week, these toner cartridges leak toner over the print copy, looks like a 2-3" wide streak of black measles spots down the length of the page. Gotta return them.

The ink was dry in several of them or at least wasn't coming out from the internal well to the tips

I had originally given this product 4/5 stars, because they started off pretty good.
However after a couple months, the blue toner started putting big lines all over anything I printed.
The picture attached is about the best I can get. Often times, the blue lines are much thicker and more blatant than this. I have limped along like this for the greater part of a year, often apologizing to my clients that my printer seemed to have puked all over the documents I was handing them. My toner has now depleted and I am happy to be ordering replacement.

Balls looked painted. They felt like they had a thick coat of paint applied that covered up the condition of the balls.  Lots of scuffing and marks appeared after only a few strikes.

Blue marker was dried up. Ironically the main reason I bought the pack!

The ink tends to blob up while you use it and there's occasionally small blotches that are left behind in your lines.

Do not buy. I went through 3 of the pack already and have to throw out majority of the prints because of the blue tint and the streaking. No matter how much edits you do this won't go away.  I didn't have this much issues with the other brand of paper. Not the mention the paper is old and the glue no longer sticks.

Thought this was a great buy, but when I went to open the blue ink it was all over the package and it was a mess cleaning it up and hard to get off your hands. Otherwise the others were great.  Maybe something can be done to clear this problem up.

The ink is a great price, and works as promised. Just be ready to ruin your clothes and anything else around when you remove the tape from the ink cartridge. I opened mine and it dripped badly on my pants and shoes. It was not just a drip or two, it was enough that my hands were covered. I had to use my hands to keep the ink from dripping on the hardwood floors, and my hands were stained black for a couple days (even after washing with heavy duty hand cleaners). Other than ruining a good pair of pants, I'm happy with how the ink works. Can't tell any difference from the ink that was supplied by the manufacturer.

Look at the photo I posted. It looks like the colors were put on with a Sharpie.

I hadn't used my pens for approximately a year. They were kept in my desk drawer. Recently when I tried to write with them, the ink had dried up. The window shows there is ink in them.

The pens seem to have picked up a bit of black from the item they were trying to cover.

BEWARE unless you want to be a smurf...These sheets were washed 10 times as well as being soaked...If you look at the pics (the one in the middle is to show they were white) those are towels my wife wiped the blue ink off my back and arms AFTER I got out of the shower...I can't deal with them anymore waking up blue...Now they say I can't return them since their 2 days out of return time..

The blue pen wrote great on our black cardstock; the pink one was ehhh. It didn't write as fine or as pronounced as the blue; The yellow one didn't show up AT ALL. I mean, it showed up for a couple seconds while writing, but then it completely disappeared.
