I can only recommend this toner. Supplied with Amazon Prime the next day. Simple, I have never changed a toner in a laser printer. Within one minute my Samsung ML-2165W has spat impeccable prints. No stripes, no spots, best print quality. Particularly positive I noticed that there are not so many security strip on the toner that you have to find once before use and must pull out, with half the toner distributed on the freshly dressed shirt. There are only a safety cap that is removed with a handle and a a mess - as is customary in many other toners - spared. Then the thing is ready to go. Even my grandmother would understand, install these toner. My next toner will be back from Angry Frog.
