Review on Miss Deer Compatible 934 935 Ink Cartridges for HP 934XL 935XL Printers - Officejet 6812 6815 6820 6825 Officejet Pro 6230 6830 6835 (1 Black, 1 Cyan, 1 Magenta, 1 Yellow) 4 Pack by Bryan Gallardo

This ink didn't work in my printer but I bought it quite a while ago. The seller immediately refunded the purchase price even though I threw away the mascara and there was nothing to return. At first I left a rather negative comment, but I had to contact the seller. Based on the feedback in the comment, they were looking for a more reliable product that didn't have the same problem as me. I should have given them the opportunity before leaving negative feedback. Especially since their customer service efforts were just top notch! Haven't tried this product since I bought another printer but will probably try again based on the seller's communication alone.
