For the longest time, I have found it very difficult to get high quality cartridges for my Canon printer. However, this site made it very easy for me to do so. They have a very easy checkout process, and the staff members are very accommodating when it comes to handling issues such as questions about the product. More importantly, the product works as advertised. The first time I bought it, it lasted more than a month with every day use. Considering that I print around 200 pages a month, the 6,000 page yield claim does hold some water. I would recommend this service to anyone interested in buying toner without a hassle.
