I personally adore this little device. I've had mine for 4 months now and use it every day and haven't experienced a single problem with it. The outside casing is made of solid metal that can take a drop or two and keep on chugging. It's also a great size, not too bulky but not flimsy either. It fits perfectly into the user's hand and when done it also fits nicely in your pocket without being obstructive. Being a small sized product though it does get warm to the touch during sessions and produces some warm vapor. The oven design reallys works, consistently vaping the vast majority of the flower loaded throughly and loading/cleaning are both a breeze.) At .3 grams the oven is big enough to get a buzz (or two, depending on tolerance levels) though I do wish it was either bigger or had a way to stash spare flower (because I like to take this on trips with me and loading another oven load in public feels sketchy sometimes.) With 4 temperature settings [360, 380, 400, 420] that are easily switched between it's fairly simple to find the perfect temp to get a great vape (mine sits at a constant 400.) The app can be used to further adjust the temp (by individual degrees) and has several modes to further enhance your experience [such as a Boost mode that guickly heats up the vape/keeps it cooking longer or an Efficiency mode that slowly increases the temp as your gaping in order to "get as much out of your flower as possible."] (though I rarely use it because connecting the app and Pax 3 is a hassle due to spotty Bluetooth connectivity and more importantly I'm trying to vape not mess around on my phone.) Now having a max temp of only 420 actually makes the Pax 3 unsuitable for gaping concentrates despite the Pax 3 being touted as a dual-purpose vape. I mean the concentrate chamber is decent and all and is actually a really good design, it just doesn't get hot enough (one needs to be in the 600's and above to get a dab like hit.) I mean the concentrate WILL melt down and you DO get vapor from it, it's just not satisfying in any way not does it produce a noticable high (in my experience.) Now using flower in the baby is where it SHINES! Since buying it the only times I'll smoke a bowl anymore is with friends and J's/blunt's are strictly for walks now due to how amazing the vape is from the Pax 3. Compared to smoking a bowl the vapor is incredibly smooth (though due to the size of the Pax 3 the vapor does get hot and can/does cause throat irritation resulting in coughing, though nothing as intense/rough as from a bowl) and once you find your right temp the high is fantastic as well. Often times I've found the high to be initially lighter/not as overwhelming/not as intense compared to a bowl which allows the high to be more functional. My only problem is with the charger. The Pax sits magnetically on top of two pins, though it has to set on a flat surface to work and it isn't held into place by anything so if hit it can come off the charger.
