Good replacement for my Hakko Fx888D. Came in a fairly thick plastic case for easy storage. I've used one tip for 30+ hours of soldering at 375C and they don't seem to wear out faster than standard tips. No rust or scuffs, would definitely buy again. EDIT: Used it for low temperature soldering up to 350ยฐC, at higher temperatures the tip degrades quickly, I would avoid temperatures above 400ยฐC.
