Hello all . I've been "lurking" on this website for the past month or so, reading the reviews for several of the portable vapourisers but each time I think I find one that is perfect for my situation I happen to find something wrong with it that puts me off buying one. I'm fairly new to the vape community. I bought my first vapouriser towards the end of last year, a Herbal Aire H2.2, but am looking for something that I can use when I am out and about. I've been looking at two in particular, the Ascent and the Pax. From what I understand about the Ascent, there were problems with some of the units that meant that the owner had to return back to Da Vinci for repair. I live in the UK so it would cost me too much money having to send the Ascent back each time it broke, if they are as unreliable as what I have been reading on this forum. So for me, that rules out the Ascent. That led me on to Pax, but my problem with Pax is that they are notoriously hard to maintain. That is a big turn-off for me. I've also read that the bowl size is huge so burns a lot of herb. I then had a look at the Firefly, but the review I read on that made it sound like it wasn't that practical for the way I would want to use it (stealthy). So I decided that the best way to work out which portable vapouriser would best suit my needs would be to ask the knowledgeable ladies and gents over here. Basically, I'm looking for a portable vapouriser that best fits the following criteria: 1. Stealth - must be stealthy. I've read good reviews about the Arizer Solo but that is not what I consider stealthy. It just looks way too big and I'm not keen on the glass mouthpiece. Something the size of the PAX or Ascent is small enough. 2. Battery life - The ideal portable vape would have sufficient battery life to ensure that I can get a good few sessions out of it. This vape would only be used when I am out and about, but away from a power source where I can charge it, so a large battery life is a must. 3. Durability - I live in the UK so postage back to the manufacturer in North America each time it breaks is not really ideal. Really I'd want something that has a proven track record of durability. Were it not for the problems with the Ascent, I would have already bought one. 4. Bowl size - I don't really want to have to put LOTS in each time I want to use it. So extra points go to vapes that have a small enough bowl size that you don't need to put cotton/fillers/etc. in to pack the herb down. 5. Maintenance - Like I've stated above, ideally I don't really want to have to clean it after every 3 uses (like the PAX) and also don't want it to stop working, or the functionality of the vape is dependent on how clean it is (again, the PAX). I'd say those are my main criteria. Taste, cloud size are important but not essential. As long as the device gets me medicated then that is all I'm after. It doesn't necessarily have to taste amazing, although that would be a bonus, but it is the effect what counts in the end. I apologise in advance if I have posted this in the wrong place. Edit: Sorry, I should have made this clear but didn't even think to mention it until DDave's post. I will be using herbs only (and only kief accumulated from grinder) for the vape.
