The inks are from a well regarded Sth Korean company & they appear to be good quality but I don't know anyone who uses this ink to give you better feedback. As a general rule of thumb if a company like Mir Aus which supplies the ciss unit you are looking & tell you what brand of inks they use then I would think you could assume the ink is worthy. Don't forget if you are not so happy with the supplied ink you can always refill the ciss unit with ink from one of the proven performers the people here recommend.
I would tend to agree with rodbam on this one and only buy what you know to be good.
Yes the Moorim ink looks to be alright but how can you tell, it is a very tempting offer however buy cheaply pay twice comes to mind.
Most of the CISS units are pretty much the same no matter where you get them from but ink is not.
Rihac may not be the cheapest place to buy inks from but you are guaranteed that it is good quality and their track record is there for all to see.
Now regarding the pigment inks, it doesn’t work in any CISS units that are available for Canon printers its for that very reason that Rihac don't sell pigment ink and if any other supplier says different then they are simply telling you porkies..
