I have used LD products in my two Canon printers for years. They perform well and are a bargain at the price. However, my last order (last May I believe) included a three G&G cartridges instead of the LD cartridges. Two failed to operate in my Pro 9000 II and one was leaking as I was taking it out of its package. I order some more the other night and they were delivered tonight (fast service). There were three G&G cartridges among the 20 that I purchased. After a call to customer service on Monday, I will be returning those three for either replacement or refund.
