If you own a compatible Canon MegaTank/ink-tank printer (especially from the PIXMA G-series) and you plan moderate to high printing volumes, the GI-490 ink is a solid choice: genuine brand, good value for volume, reliable supply. However: Double-check your exact printer model is listed as supported. Make sure the ink bottle series matches your tank/reservoir system (mechanical bottle necks may differ even if “technically same ink”). Ensure you store the bottles properly (cool, dry, sealed) especially in environments with high heat/humidity.
