I have acquired and use these bottles, and they are a big time-saver for me.  However, I find that the nozzle for the MK (carbon black) bottle occasionally tends to clog and then I have to use a separate syringe for that refill.  Regarding the separate subject raised concerning a light coming on -- to indicate a low-ink cartridge -- I use my cartridge re-setter to clear the "offending" cartridge.  In fact, when refilling my cartridges, I always re-set them before re-inserting them.
