For pure stealth I really like the Vaporizer.
I'm going to pick up another one and carry one in each pocket! One black, one stainless steel. Oh and another one for the Nibbler GN... It's my favorite thing to use with the Globe and GN because it is so light!
This is the best UP tech product yet for those who want to go for a hike or throw something in a Camelback to go biking or slip into your snowboard jacket pocket. It holds a good amount of concentrate, over 2x as much as I'd put into a KISS cart; the battery lasts long enough to get through the full load if you choose, and its incredibly easy to use, and you dont worry about breaking it becuase it's so inexpensive to replace if you crash on your longboard with one. Its less painful then the road rash (personally proven)
I'm now using the Vaporizer, Persei shorty with KISS mini, Persei full length with Herc and Nibbler XL, and 8 with Okeanos as my go to devices. I've cut out everything in the middle.
