Capacity
I can not remember to have ever owned a printer in which the ink cartridge has kept nearly as long me. Of course, I did not count the pages, but felt, the HP 950XL an excellent capacity. Before that I regularly used a Brother laser printer. The black toner has held definitely no longer than the ink of the HP 950XL.
Handling
I compare the handling of the HP 950XL with the toner of my former Brother laser printer and my private Canon Bubble Jet Printer. Replacement of the ink cartridge could easily not be. With a slight pressure on the empty cartridge in the printer, this is unlocked and can be removed with two fingers. Schutzige finger (by "dripping" or "toner," - as in my previous several printers) are not to be feared. The new cartridge is inserted in the same way in the printer. The most complicated is definitely opening the package. And even that is simple, since there is neither an unnecessary packaging are, yet adhesive protective strip must be removed.
Price-Performance
25 Euro are definitely taking into account the capacity of a fair price. The Brother laser printers I'll definitely not gone cheaper. So far, there seems to be no compatible cartridges from other manufacturers. Even if I can not imagine that it might make sense to avoid it to me.
