Your service is great. I use to buy ML-1610 cartridges out at Costco.I noticed that I was running out of ink so quick. I was spending so much money buying ink. I felt that the cartridges were not being filled all the way. So I decided to try to find another source. I looked on the internet and found you. I ordered your Samsung ML-2010 / ML-2510 / ML-1610 / SCX-4321 / SCX-4521 - Dell 1100 Toner Refill Kit. Now I may refill my cartridge 2-3 times. I kept waiting for the rfilled cartridge to run out of pouder. It lasted twice maybe three times longer. If I could prove it I would sue Costco or the supplier for cheating the consumer. I just don't have the proof. I can't tell you how much money I spend on their half filled cartridges. Anyway I am very pleased with your product and service and will continue to buy your products as needed.

I ordered your cartridge it was 25 mils just like the Costco one. I kept waiting for your cartridge to run out of ink. It lasted twice maybe three times longer.

The Six-Color Inkjet Refill Kit is a very good product. Good price. I'll order again when I need more.

Dear Sir(s), I just want to thank you for the "Easy Refill Kit" which I ordered for my Desk Jet 610c. It was a breeze to use and the resulting quality of the "print" was absolutely perfect. Thanks again for a great product!

Very pleased with your products. I was ready to junk my printer until I used the cleaning cartridge I ordered from you. Now, it's back to printing clearly, and with the right mix of colors. I'll be back!

I recently received the Fillserv Tri-Color Inkjet Refill Kit and I found the refill process to be very easy to follow. My refilled ink cartridge works like new. Thank You for a geat product!
