Leakage and what is here else so I reviewed can in no way CONFIRM (also about other products) and is my own private opinion, not understandable partly something funny written / for me.
The product corresponds to 100% of the specification and works with the printer (HP 6500) perfectly. The "warning" of printer cartridges foreign use does not bother me ... it is a time "OK" and even if you do not wegklickt this, the printer prints (job per PC / MAC sent). Levels are as far as I can tell, it appears correctly. The printed image matches with 90g / paper also good (have no photos printed it; only letters / text pieces).
Strong buy recommendation!
