Colorful finger and blurred pages

1. When releasing the orange safety cap standing in this case to date each cartridge exchanged the color in this and I would not use the cartridge without dab this beforehand. The cartridges are not completely filled, which I not again be negative ankreide (however, this could be the point criticized in the following explain). Unfortunately, a cartridge dropped so much that I had the same colorful finger. I would have dressed better gloves (but afterwards it is well known, always smarter)
2. The durability was better at my old cartridges: I wanted to print me a book, which admittedly is very colorful. That, however, all the colors, and the large black hold only about 40-70 pages, but then made me disappointed. My old cartridges had managed compared to at least 100 equivalent pages.
3. Print quality is bes ........ The color runs partly because they apparently do not dry fast enough or for whatever reason. At first I thought it was up to the template. Then I thought my printer was perhaps dirty or similar, but also a cleaning etc. did not bring anything. Above all, the print quality was the old cartridges always 1a.

I write reluctantly negative reviews, but I would have been happy even before those reviews to have been read.
The price is very tempting, but I will definitely not buy these cartridges. Especially when you consider that there are others in the same price range, but perhaps more hope to find better quality despite low price ;-)
