Review on LxTek High-Yield Ink Cartridge Set for HP 950 950XL 951 951XL (5 Pack), Compatible with OfficeJet PRO 8600 8610 8620 8630 8100 8625 8615 276dw (2 Black, 1 Yellow, 1 Magenta, 1 Cyan) by Jeff Labore

I bought these printer cartridges to save money . I used to buy the Office World brand and it has worked well. (Although they didn't last as long as HP, but were close). This brand has impressive reviews. My test and rating shows that they are below average. At first I couldn't get my HP 8600 to print anything. The paper came out blank. After 9 head cleanings, the print quality is unstable...this means the colors don't repeat and the lines run. I would not buy again. I just found out Office World is back in stock and I will buy them next time.
