I'm not a fan of not being able to control the settings directly on the device either. It seems to still work without syncing. There is just no way to adjust the temperature. Yeah, the GPS thing is weird to me as well. No, didn't see a find your vape function anywhere in the app. This vaporizer is considered a true convection vape. Even on the highest non-concentrate setting, I've only gotten vapor, and it's been fairly cool for the most part, no burning the mouth or throat. It will blacken the herb if you don't stir the pot. I'd imagine it can burn if you just left it in there and kept drawing away, but the heat turns off after you remove your finger(s) from the sensor at the end of your draw, so you aren't cooking bud and wasting vapor in between pulls. The fragrance for me changes from piney (GG#4) to a cooking wood type of scent as the bud is used up. Doesn't smell like smoked cannabis at all. Exhaled Clouds dissipate quickly as well. Definitely won't go back to smoking. This is like a 90% cleaner pull, you aren't getting any burnt byproducts when you inhale.
