I don’t have any Problems. Every Filament works well.

The nozzle arrived yesterday, and I immediately installed it in my Bambulab A1.
So far, I’ve only printed a few things, but I can already say with confidence that the nozzle prints much better than the original one. I believe the prints are more precise, and I haven’t noticed any of the occasional issues that used to appear.
I’ve already shared some photos and insights about the Super Ruby Nozzle in a Facebook group. If you receive any orders from the Czech Republic, it might be thanks to me. Thank you very much for a great product.
If this nozzle ever wears out, I’ll definitely try your diamond one as well.

not tested yet but support very helpful to fix a mistake in order
