I got a stainless tip on a previous order. Don't know if I just got an odd one or if the whole batch is this way but it had lube in the hole or oil or something. I just put it on my PV and went to take a vape and ACK! Awful nasty taste like I'd squirted 3-in-1 oil in my mouth. A quick bath in alcohol I keep handy for my weekly external cleaning did the trick and cleaned it right up. But thought I should let folks know to be careful of the SS tip.
