The AVLP did seem to fly under the radar for the most part, but the people who did get it seemed to like it. The only complaints I've really seen are about cleaning it, and a couple mentions of not liking the fabric which is admittedly not a great choice hygiene-wise. I find that the majority of the issues with cleaning are addressed by using the dosing caps, but it is the biggest weak point in my opinion, and looking at the AVLP2, that is no longer an issue.
Some of the hesitation comes from the past and the original Legacy vape, before the Legacy Pro was released. The Legacy wasn't a great vape, so people didn't want to jump on the pro version of that vape.
If you look up the Legacy Pro on reddit you'll see the entire range of opinions on it. It's pretty positive, and most of the negatives look to be resolved with the V2 model.
I am hoping that someone out there is intrepid enough to tear down their AVLP2 so we can get a good look at its internals.
