Better than a fiber cut off wheel? checking out the Ezarc Metal Master

trying out the Metal Master all Metal cut off wheel from Ezarc. the problem with fiber cut off wheels is that they don't last and can break and go flying. does this fix that problem?
how good does it cut through galvanized pipe and axle bearing.
this Metal blade has diamonds on it like a tile saw blade. it does not get hot while cutting.
it cuts fast and easy.
here's a link if you want to try one
