We have never been disappointed by these cartridges. I've never done a side-by-side comparison (and it would be hard to do one) to see if they do actually perform (quality, # of pages, etc.) as well (or close to as well) as OEM, but they are soooo much cheaper. I can't imagine an OEM would last 4x as long, because they are 4x the price!

I'm sure in some ways these are not as high-quality and maybe not even quite as high-yield as OEM, but the savings vs OEM are SO enormous that it is crazy not to use them. I only ever buy these, and never OEM. In a few rounds of buying these instead of OEM, it practically pays for a new printer anyway! Cannot recommend them enough.
