So the alternative providers are naturally more attractive, priced at least.
In recent years, their quality was getting better but, contrary to conflicting promises, just not as good as the originals.
Now here many will not agree with me but it's just so (for me at least).
I'm really not technically non Siert and have always had the experience that the alternative providers eventually something goes wrong.
So also currently with my Canon Pixma 6250 when unexpectedly a new PGBK cartridge (Peach) refused to serve.
I have immediately ordered the original and vowed to use only (and grudgingly) original cartridges.
Therefore clear recommendation for the quality and a star deduction for the price!
