My cartridges were empty, and I needed a new one. The original cartridges were good, but also very expensive. Here at Amazon I came across these cartridges, not even cost a quarter of the originals. I was skeptical, but the reviews made me but then order. The cartridges fit well in my SX235W. No wonder they are up on little things (such as the clip) as the original ones. When checking the ink levels, they will even appear as "original". Accordingly, there were no problems during printing. So far, I tested only the black cartridge via text expression; but could find no real difference to the original ink. However, I think that just color prints on photo paper will look better with the original ink (without having tested it) ...
When the printer rather than just "professional" use, but only occasionally texts and some pictures prints on plain paper, so I submit a strong buy recommendation for these cartridges!
