Kind of Buzzkill on the tip change, I was going to install the plastic first thing 'cause I just don't like the metal tip period and can't afford to go out and buy one, my allowance for this habit is shot with the PRE-ORDER trend and I seem to have been hornswaggled on that deal.
Someone looked up "metal" in a chinese-to-english dictionary, and came up with "iron".
Asking them to specify should (hopefully) get a more accurate description - but from all accounts, it's chromed brass.
I haven't had the chrome wear off yet, so I'm not worried about lead leaching - but they certainly shouldn't be calling it Stainless Steel if it isn't.
