Most disappointed to receive a white boxed product with worryingly unprofessional descriptive label and distorted HP logo. Initial impression was not good. Impression was that the unit was not a genuine HP toner unit - certainly not as illustrated. Seriously considered arranging a, 'returns' procedure, but hassle involved outweighed the decision to go down that route. The toner powder may be genuine, but without any way of knowing for certain, a suspicion remains that it is not genuine. However, the unit is installed and working as expected and the print results are as expected.
Recommend buyers go for sealed pukka HP products to be certain that, 'what you buy is what you get'. Or if you don't mind refurbished units buy to that description.
