Product arrived on time and as described. Product works well in my Brother printer. Time will only tell if this product will be safe for my printer. In the past, I owned a older model of Brother printer, purchased generic cartridges and eventually the printer jammed up. I never took it in for an evaluation so I will never know for sure if it just died because these products are made to be disposable or if the generic cartridges jammed it up. I choose to take this gamble of purchasing generic cartridges to save lots of money on cartridges. I can't give the seller 5 stars because I just don't know the long time effects on my printer.
