Durable Build
Hardened steel feels much stronger than brass. Expecting this to last much longer.

Recommended Upgrade
Essential if you print composite materials. No clogging issues since the swap.

Good Value
Works well but heating took a moment to stabilize during the first print. Otherwise solid.
