I own an MP630 Canon printer. Like everyone else, I wasn't impressed with the cost of replacing all 5 ink tanks; as everyone knows, this is where the manufacturers make their money and rip us off. So I very cautiously looked at my options with compatibles, which (probably quite rightly) have earned a bad reputation.
I'm big on my photography and top of my list of priorities was print quality, I can't really compromise on this and would have to stick with Canon inks if the compatibles didn't perform the same or better.
After much research I decided to run with these compatibles. I already had an A4 colour print using my Canon inks and Canon glossy paper, using a professional high-resolution test image designed specifically for testing printer and ink/colour performance. I replaced my Canon inks with these compatibles and repeated the same test on the same paper.
The results are outstanding, identical to the original Canon inks if not better in a couple of areas of the image! Amazing. Tones are bang on. I'm now testing ink fade by placing the two images in direct sunlight for a while and will update this review if I see any degradation.
The inks came well packaged, branded as "Computer Essentials" and are made in China. The tanks themselves seem to be the same build quality as Canon's, complete with ink guard (which needs to be twisted off before use) and chip to inform the printer and PC of ink levels. Perfectly straight forward to install.
I'll certainly be purchasing these again in future. Printing all of my colour photo's just got a lot cheaper.
Hope you find this review helpful.
