Cool Toner Compatible Toner Cartridge Replacement for HP 12A Q2612A for HP Laserjet 1020 1022 1018 1010 1012 3050 3015 3055 3030 MF4350d MF4150 MF4370dn D420 MF4270 Printer (Black 4Pack)

4 cartridges and each last on average for 3 months and prints 2000 pages. Staples cost is $90 per name brand cartridge - prints 2000 pages. $10 per cartridge v.s. $90 per cartridge, you decide.

I was extremely dissatisfied with this product. All the ink cartridges were empty. I was unable to return this product in time for a refund because of a death in my family. Opened 2 of the cartridges and they were empty. What a shame!!!

You can't beat these for the price. Less than $10 each. I've been using these at my business and getting approximately 1100 pages per cartridge, which is less than advertised, but still a great value for the money. I have been ordering Cool Toner cartridges for a few years with no issues. The last time I ordered, one of the four cartridges was defective - left black bars across all pages. I contacted the company through Amazon and after explaining the issue they promptly sent a replacement.

Our club prints out 50 or so pages a day and a cartridge lasts about a month. These are easy to install, and work consistently with good quality printing. We shake the cartridge to get more mileage out of the toner. It's definitely worth a try if you're considering trying out a less expensive option.

I love this product. It works great and is a good value for my money. As a teacher I am always looking to save money

Price was reasonable for the number of ink cartridges

I used to pay full price for one HP toner. Now I purchase Cool Toner and receive four for an extremely reasonable price! They work out to $10 each! I highly recommend.

I have a HP inkjet printer. I can buy four of these cartridges for what I would Pay for one name brand. They install easily and the resulting print quality is excellent
