has anybody heard of Olympos and Graphotech airbru

Have you heard any of this brands?
can you comment on them?
if not which one would you recommend in th 150-200$ scale?
thanks

I have never heard of Graphotech, but Olympos I have heard of.
The Olympos I believe are made in the same factory with Iwata so they are very similar to Iwata’s quality.
Sorry I can’t help you out more as these brands are not real common in the U.S.
