Looking for cheap cartridges for my Epson Stylus SX510W I stumbled across this property and thought at first I do not see properly. So far I have always have to cough up double-digit amounts for my cartridges and have these cheap cartridges therefore not trusted. But now I'm so glad I tried it. The printer detects the cartridge directly and they fit perfectly. The black one tick is brighter than from the original cartridges, but this really does not bother me at this price.
