Smart Ink Customer service is fantastic. I've had many print quality issues using this ink set in my HP OfficeJet Pro 8210 printer. If I don't print for more than 24 hours, the colors come out wrong, faded, and streaked, and I have to run the printer's print function Clean the printer" Function. heads", sometimes more than once to keep prints in good condition. came out clean. I contacted Smart Ink support and they responded quickly, very politely and very helpfully. They asked a few questions and asked if I could send them a photo of one of the bad prints (I did) and then sent me a new set of ink cartridges for free. They were also fantastic in terms of follow up and seemed really invested in solving my issue. I only received the replacement kit last night and haven't had a chance to install and try it out yet, but will update this review when I do.
