I got it today!
First impressions: smaller than I expected, very attractive, fits well in my hand. I couldn't wait to try it out, so I dripped a few drops of ultrapure unflavored 12mg vg on the included atomizer and took a drag. Yuck--I don't like whatever madvapes puts on their attys. Blew it out, washed it, dried it, dripped, tried again. A few pulls and the bad taste was gone. And wow, great vapor production, warmer than with the 801, but very tasty! I like it so far.
