I like unregulated. I have a ton of mech mods, but I also like unregulated box mods. Its just the way that I build my atomizers that makes them work so well. And I don't like having to think about volt limits, amp limits, etc... i just use ohms law and build accordingly. Lately, I have been building very low (.1 ohm range... lower than any regulated would fire), but I have been using these builds safely on unregulated boxes that take 2 or 3 parallel high amp 18650s. You don't need to build that low for a great vape though, I am just having fun with my unregulated mods. I just like them. And I like building atomizers for them. And, sometimes, I like building my own mods without any fancy chips. I think unregulated requires a bit of skill to vape exactly the way you desire, but I prefer it this way and don't need some beginner device to hold my hand.
