I wear cargo pants a lot and think a box will carry nice. I'll probably have an itaste vtr someday soon and should have gotten that vs the MVP due to the height with a clearo. I just watched a RiP Trippers vid on the sigelei zmax and it looks good with a decent price but it's too long for my carry preference right now. Give me another few months with this stuff and I'll have unit for everyday of the week!
I have a VTR and enjoy the heck out of it. Not to mention being something of a klutz and needing something solid. And that they are. Some say they're too heavy and bulky but I don't agree. My opinion, they have a great "heft" and the recessing of the tank protects it better when I inevitably knock it over or off a table or whatever. I'm creative at finding ways to bounce things off tables and stuff.
Also, if you're concerned about battery life, one reason I went with a VTR is that 18650 batteries--even high end ones--are pretty cheap. The draw back of the MVP (which was on my short list when I upgraded) is the battery isn't replaceable. A Sony with the same capacity as the MVP is about $13 (like here:
SONY VTC5 18650 2600mAh Battery - Flat Top - 30A). Since I discovered I'm hard on batteries, it made more sense to go with replaceable ones. A dirt cheap MVP (like at 101vape.com) is still around $40. That's three or more 18650s.
And my VTR travels in a jeans pocket all the time. No problem. Though there is, also, a belt "holster" but I never got round to getting one.
(Come to think... shiny metal thing in a hip holster... that might lead to difficult explanations... like while on the ground with a knee in your back when you were just going to make a deposit at your bank?)
