Hi
Thanks for reaching out. The Pax gets great reviews (For original units at least - There are a lot of knock-offs out there) from end users / on the forums etc. but I can't truthfully answer your question as I've never had one to play with.
I use the Da Vinci original as well as the Ascent regularly and they are both solid vapes. You have a little more control with the Ascent and it features an all glass pathway which some users prefer. The Da Vinci V2 for the money though is rock solid and it does dry herbs and oils etc with the included Oil Cans. They have come down in cost at wholesale since Da Vinci launched the Ascent so I am offering them @ £99.95 / 0.56BTC now when they used to be £149.95 / 0.85BTC. For that price point they are one of the best digital options out there IMO.
With regard to the Pax they are now being made available to EU / UK through selected distributors. I expect to have stock in a couple of weeks or hopefully by August at the latest.
Let me know if you need anything else. I'm always happy to talk vapes.
Thanks for your answers. What's the difference between the Da Vinci 2 and the Ascent? If you could do a review of the Ploom when you get it that would be great. I really don't want to buy a vape and it not be what I wanted as it would just be a waste of money. The Pax or the Da Vinci are definitely the two I'm looking at the most but am open to suggestions. As long as they're fairly compact and actual vape and not burn that's all I really require.
