I bought these expecting that they would at least be recognised and accepted by the printer (Canon MG6150) but that the ink levels might be incorrectly reported, probably showing the new cartridge as 'empty' (as seems to be common).
Very pleaaed to report that the printer itself and the monitoring software both report a working, full ink tank!. Print quality seesm as good as before. Delivery from Ink Jungle was very rapid (and free).
No idea at this stage how long they will last, but considering these cost 1/3rd of 'originals' I am willing to accept slightly poorer life. Then again, you could never tell how long the originals were really going to last as the monitoring chip had a terrible habit of issuing 'low' warnings only weeks after inserting (with relatively little use), moving to 'empty' some 6-8 weeks before the tank actually ran out, so whatever you do, don't just replace the tanks when the printer tells you to - wait until it actually stops printing!!
