I wanted to test the ink cartridges. They came very well packaged, each in a thick plastic, and all in another thick plastic. I had some problems unpacking: the ink flows above or below interchangeably. Must wear gloves because the ink stain. I put two cartridges in my MP540 printer who immediately recognized them: no problem. I hoped that the colors are beautiful, but alas, my printer is not the case and color pictures are pretty aggressive. It's a shame because their price is low.
