DUPE buyer beware ...
I purchased HP ink on Amazon. Weinkjoy was the seller. What I received was a DUPE for HP cartridges. The HP printer rejected the ink. I followed up with AMAZON, who referred me to Weinkjoy. Wilson at Weinkjoy requested information which I sent. Instead of resolving the issue the inquiry was closed. Lesson Learned - DO NOT BUY PRINTER INK FROM AMAZON, it is a DUPE, imho
