Well, I had just enough of the old bottle to turn it into "very mild cherry" flavor and hey, it's no too bad.
I'll keep using TW, for sure, the shipping was great and I think the extent of my sole bad experience was just bad luck.
You know, the tank style cart has won me over. I was slow to try them, but my original atomizers are still working for me, so I had no need.
I may just make do with the normal atomizers, because not having to refill so far as been really nice.
