mentioned reach is wrong

I can not recommend this product, because the range specification does not match the reality and the printed image after about 700 pages is no longer satisfactory ..
By Erstausstattungtoner (mentioned reach 700 pages) I could successfully print 450 pages. This ratio basis, should have come out about an effective range of nearly 3,400 pages in this toner.
The toner has, however, started after about 700 pages (after reset as per instructions), give a streaky image. After 925 pages, he is now already at the end. The recommended by the supplier reset did not affect the print quality.
Unfortunately, I have a friend recommended this product. With him were the same problems with to short range and banding in the printed image. I have therefore complained about the article at amazon and returned.
