Of the 5-6 'pocket portables' I've used (no e-cig types), with the latest being the Puffit, plus a couple of flame fueled models, this is the only one that I've actually picked up to use in the house (if an AC model is handy), other than an occasional mini or micro hit from the MF. I've put up with the 'end of the bowl taste' on the iolite/wispr, in order to get the job done, but the DV has very little of that. The smaller bowl factors into that, I imagine, but there's still more than enough room in the hole for a good session for me, sometimes two. But that gets into personal preference and tolerance and shouldn't be used as a measuring stick. But I find the DV hits quite high in vapor/air ratio for a portable (the Supreme is top rate here but a PITA to heat up, as well as dangerous when you're high) and adding in ease of use, I'm very happy with it. We'll see how I feel down the road when the batteries quit providing a satisfactory operation time.
