Bests & Worsts Reviews from Amazon

Works great in my HP Envy 5530. I read many of the reviews about how this combo pack (black & tri-color) didn't work in some printers. Then when I entered my printer's model number into amazon, it told me that it wasn't compatable with my printer. I thought it was weird, because I thought all "61" ink should work in all printers that take "61" ink. I decided to take my chances and purchase this HP 61 ink set anyways and I am glad I did. It works perfectly in my printer. When I received the ink, I checked the side of the box and my printer was listed. Here is the list of printers that are listed as compatable on the box: HP Deskjet - 1000, 1010, 1012, 1050, 1051, 1055, 1056, 1510, 1512, 1514, 2050, 2510, 2512, 2514, 2540, 2541, 2542, 2543, 2544, 3000, 3050, 3050A, 3051A, 3052A, 3054, 3054A, 3056A, 3510, 3511, 3512. HP Envy - 4500, 4501, 4502, 4504, 4505, 5530, 5531, 5532, 5535, 5539. HP Officejet - 2620, 4630, 4631, 4632, 4635. I hope this helps and clears up the confusion that everyone might be having.
