I use the cartridges for my MX 925. The cartridges are recognized by the printer properly and have experienced no loss in the third run. No stripes, no problems with the recognition. A direct comparison with the last printing of the original cartridge in the photo-term results when comparing test with these dramatically cheaper cartridges no discernible difference in the printed image and quality! The cartridges are individually welded and have the same assurance of plastic on the bottom, as well as the closure for air intake on the top. When preparing for the onset it does not come to drop formation as with other replacement cartridges ... In the long-term test and number of pages printed, I can not tell the difference with the original cartridges! I am completely satisfied and would recommend these cartridges without any restrictions for use. Absolute buy recommendation!
