Functionality: My printer (Canon MX925) the Pripa cartridges has detected directly and without compatibility problems. Longevity of these cartridges equivalent to the longevity of the original cartridges. Print quality in b / w and 4/4 on leaf (80g, white u. Recycled paper) and photo paper is at least equivalent to the original cartridges.
Processing: The ink cartridges are equivalent to the processing with the original cartridges leading printer manufacturers. An advantage I see in the transparent cartridge housing. Here it can be seen at a glance whether a replacement is necessary or the printer is set too sensitive at the announcement of empty ink cartridges.
Conclusion: Good quality at a reasonable price. For the home office area definitely a good alternative to the expensive OEM cartridges. I am annoyed that I bought for many years the overpriced branded products.
