Toners arrived quickly and better packaged than Dell products! I like that there are two black toners in the pack as it is obviously the most used. So far I've only installed black. It works great and I couldn't be happier. Why should I pay Dell's price when they're available at a fraction of the price? I will definitely order from this supplier while I have the printer! UPDATE: One of the cartridges started printing very weakly after just a few weeks. I emailed Toner 100 and got a call the same day! The gentleman who called was very professional and finally told me not to worry about ordering from them as their products come with a 1 year warranty. The defective cartridge will be replaced! That excellent customer service is hard to come by these days. I not only sold products, but the seller!
