Just a public service announcement. The new plastic in the 2.5 still leeches and cracks with some juices. I cracked 2 over the last week with mtbakervapor mountain dew and arnold palmer juice. They don't haze up badly but they crack at the base of the threads. The drip tip also melts pretty quickly although I think they are unchanged from the old version. It's kind of disappointing as I enjoy these juices. I use vivis pretty exclusively now so I guess I'll have to live without these types of flavors. I do have a metal vivi with an aluminum drip tip but I worry about the small "rubber" spacer just above the atomizer and the O ring on the drip tip breaking down into the juice.
