I bought an off brand and it made a mess of my printer. So now I have this HP brand cartridge and am back in business. I surely won't buy an off brand thinking I am getting a deal again.
The product is excellent once it is installed in my HP printer. The online purchase form and its related shipping choice options are very easy to use, very customer-friendly. The timeliness of shipping is almost always reliable. On the other hand, the product is hugely expensive and the price no doubt includes an excessive profit margin for HP. In addition, the product does not print as many pages as advertised and must be replaced often, always with "sticker shock."
