To me the buzz pro is all I need. The analog adjuster is so natural rather than having to go into a menu. You just roll your thumb for more or less heat. I have all types of technical mods but the buzz is my main device especially when I want the mod to just shut up and work. It's made in the us, was the first vv, to my knowledge and they are made in small numbers. It also has the look of a nice tool. I like my mods to look nice but in a workhorse way not a fancy, don't get it scratched, sort of way. The company is great as well and know who I am. The mod is modular meaning I can replace any part myself, it is red, and engraved, haha. I used to be into exact wattage and such, but I just don't care or need that. I still have those types of mods for testing rebuilds and such. I also have a dual 18650 altoids tin made by Justin at vapeunited the tin is solely used for crazy power. I vape my 3ohm hh357 at 6.6 to 6.8 volts as Hannah suggests. I'm also still amazed at how well my ego c twist is working after all the charges and beatings it has taken. It is a clone and i dropped it in the toilet but it still Vape says with power. I rebuild my kangers and evods with ten wraps and no resist wire, vape the hh357, have a DRA XL on the way, and am ordering an amp tank whenever they re in stock. Seriously though, I've had my buzz pro for a while, and the infatuation of it hasn't worn off. It deserves another look considering the quality of it and the fact it is only 79 dollars now instead of 120. No bells and whistles, just a joy to use, simple functional, pretty. Sorry for the long post.
