Learn the hard way !! I've always known it actually

Allso first advance. I bought these cartridges in good faith, as is explicitly called my printer in the product description (Stylus SX 235W). Yes, I've always had a bad feeling when it came refilled cartridges to purchase, but as always in life you have to learn by experience.
After four days, the (stock) cartridges came with me. And now I have to say not one recognized by the ten cartridges of my printer. Of course I could return the cartridges now and replacement demand but therein lies the rub for me. If it had now been one or two cartridges that do not work OK !!! but every ten is kind of annoying. For a product of ~ 12 the effort with cover letter is repackage towards the post and back and then to let me possibly even expect questions like - do you have after reading the manual and / or read the item description properly. Nerve! Nerve!
No Thanks! Pay dues and learned from it! Thanks for nothing and caution in these Patonen.
The one star is for the have arrived at my cartridges.
