Review on 🖨️ HP Q7551X Toner Cartridge - High Yield, Black by Phil Show

One of those cartridges didn't print at all but was full of ink. It was a waste of time. This company will not refund my money due to the 30 day return policy. But I ordered two for 13,000 and how the hell did I use 26,000 in one month. So, after 3 months, when the first one ended, I opened the second one and nothing. I have a feeling they might cater to this because you can't open them without using them or they dry out. If your product is good, this should never happen!
