Nobs is good because they only use rod-shaped NHA, not needle-shaped NHA which has a worse safety profile. Safety profile is important for anything nano
IDK how to tell what brand uses what type without independent testing or taking their word for it. Several makers have come out and said needle-shaped is cheaper to buy so if a brand has 10% formulation as opposed to 1 or 3 or 5%, it is more likely to be using needle-shaped. (And there is a separate conversation to be had whether 10% is needed/ideal concentration anyway)

Is there anywhere I can learn more about NHA shapes? I currently use Apagard Renamel.
