I have waited a reasonable period of time to see if this cost-effective solution is also a. I must say that the cartridges do not meet my quality performances. Today I have for example the second cartridge must dispose of unused because it was centrally broken and the pellets out trickled. That's ever happened to me earlier this year even more extreme. If of 13 cartridges already 2 are now unusable, then the reject rate is well over 10%! I just hope that the four unused items have no shortage. Whether that has happened in the production or shipment, I am interested only in passing. Fact is, I can only use 11 cartridges. Very annoying!
