4000 pages? Are You Kidding Me? Are You Serious When You Say That!

I bought this toner due to the customer reviews and am totally disappointed. As mentioned already in the customer reviews and I had my doubts after unpacking the toner. The toner is significantly lighter than the genuine toner from HP. But I've already bought the toner and need him urgently.
So pure and toner print. After a relatively short time I've already seen the first strip. I have of course not counted, but I've definitely printed much less than with an original or another refill toner. For me, this is fraud.
I say just finger away and prefer to buy from a dealer a correct refill toner.
