Really appreciate the fast service. My business was hurting because I had no ink for printing plans and was unable to find ink until I contacted swift ink. The ink cartridge works fine. Thanks for the 5 STAR service

Very Appreciative!!

Firstly, you Folk's still support my Ole HP DesignJet 430 which is amazing. Second, you are very generous in providing additional cartridges when one fails on me due to the antiquated nature of the remanufactured chassis. Third, the delivery time was only 2 days, and I didn't pay for that rushed shipping. Thank you very much! I wish all the suppliers I deal with were as amazing as you Folk's!

Swift Cartridge Replacement for HP 51640A Black

I received my order from you last week. A Replacement inkjet cartridge for my HP 430 DesignJet printer. HP 51640A. As you know, these are no longer in production. I’ve tried replacement cartridges from several other vendors, some new but expired, some remanufactured. YOUR cartridge is the only one that I’ve tried that actually works! And it works perfectly! Thank you for that! I will keep you at the top of my list of preferred vendors!

Legacy machine using ink cartridge

Ordered an ink cartridge to use in two months. Hard to find so will re-review when I use the cartridge.
