The silicone grip and slim profile make it very easy to pack and throw in your bag. The mouthpiece makes a great ash catcher – haven't had any gross surprises. However it is a *taster*, so it doesn't fit *a lot*. I recommend a small storage puck to compliment it so you can keep refilling along the way. Overall – would highly recommend.
Upgrade Option: If you have a higher tolerance, I'd also recommend leveling up and going with GRAV's 16mm Octo-Taster (which 420Science also sells). Same aesthetic, but fits a surprising bit more and has an awesome glass screen.
