Product worked perfectly the minute I installed it. My 6-year-old printer lives again, as good as new. Seller was excellent in timeliness and helpfulness. Good bargain.

If you have a Canon bubble jet printer don't let it sit idle because if you do the printhead can (will?) "dry-up". Finding the prhd is not so easy and they cost $50 when all is said and done. I am very satisfied with the replacement; now I can print black text once again. I recommend this product.
