    It's all good and I really LOVED my Twists except for a few issues...IMO a good PV...maybe the issue isn't the Twist but my eyesight :facepalm:

    that i will admit: its hard as hell to see those numbers on the twist, however, i generally twist for taste with that, and use my mods for dialing in sweet spots...the only real issue i have with them is the button sticking issue they have, other than that, a really nice device indeed

    Greetings Fellow Canuck! Welcome to ECF!

    1. The 2.4 and 1.8 heads both work well with the Twist. I've actually found the 1.8 work a little better but it would be best for you to try both and see which you prefer for your style of vaping.

    2. The 2.0 had the air hole moved to the 510 connection and it works well. The 2.5 was a mythical number created by GV to designate that they used a different plastic for the tank. The 3.0 designates that the center post is the correct length (finally, Lol) and all the wicks are long wicks.

    3. Two chargers? Ever notice that skydivers always take a "reserve" chute with them even though they know that the "main" will work (obviously they think it will work, they wouldn't step out the door, otherwise) Lol

    The numbers on the Twist are easier to see in natural light but nearly invisible in fluorescent lighting or low light. You can Twist the dial all the way, to either 3.2 or 4.8, and 1/3 turn the opposite direction will put you at 4.0 volts. The Twist is tuned by what tastes best to you, not by what the numbers say.

    Congratulations on your progress!

    Relax, Enjoy!

    I've noticed my button sticking a little bit too. Have not noticed it in a few days. Hopefully its working itself out lol.

    it happens, they stick....poor button design is the only real qualm i have with the unit, of course i use it primarily as a backup, as i have a vector, a lavatube, a home-made pipe mod i'm working on, and a provari on the way...but i keep the twists because they are quite simply the best mid-sized unit i've found...although i am looking into getting the ego-VV passthrough from ljesmokes to have a VV passthrough.
  6. I have also really loved my 2 twists and mainly use a vivi nova v2.5 with the 2.4 ohm head and vape about 4.5 volts and its good! My Z-max will be here tom and my twists will be set aside for awhile and i am gonna try a carto tank setup!

    See if this does anything for you.

    From a previous post of mine:

    [Simpler version: turn the knob to higher volts for a warmer vape, lower volts for a cooler vape, or to compensate for variation between "stated" resistance and "actual" resistance of a coil].

    This can all be demonstrated by a very simple formula that related "Ohm's Law":

    Volts time volts divided by resistance (rated in "ohms") = watts (heat) at/in the coil.

    Vaping at 4 volts with a 2.0 ohm coil would give 8 watts; 4 x 4 / 2 = 8.

    Consider the three heads in the Vivi Nova; 1.8, 2.4, and 2.8 ohms:

    With a Joyetech eGo-C Twist, or any other variable voltage device, you can achieve any wattage you need to get a good vape, even if the "actual" resistance of the "heads" varies from the "nominal" resistance of the heads, which it almost always does.

    I'd say that most people vape at between 4 and 8 watts per coil. Notice how 6 watts can be produced with a Joyetech eGo-C Twist (or any other variable voltage device) with any of those three atomizer heads. This obviously can't be done with a constant-voltage battery.

    3.28 volts x 3.28 volts / 1.8 ohms = 6 watts

    3.79 volts x 3.79 volts / 2.4 ohms = 6 watts

    4.09 volts x 4.09 volts / 2.8 ohms = 6 watts

    Again, a constant voltage device obviously cannot do this, so please do not buy one unless you MUST have a ciggie-look-alike".

    Or with a Twist and a Vivi Nova with the 2.4 ohm atomizer head:

    3.79 volts x 3.79 volts / 2.4 ohms = 6 watts.

    4.09 volts x 4.09 volts / 2.4 ohms = 7 watts.

    4.38 volts x 4.38 volts / 2.4 ohms = 8 watts.

    In rounder numbers: 3.8 volts gives you 6 watts, 4.1 = 7 watts, 4.4 = 8 watts.

    (In "real life" though, you just turn the knob until you like the vape).


    "3. Someone mentioned getting two chargers. Is this really necessary due to poor quality or was the poster just being paranoid?"

    That could well have been me; I always recommend getting two chargers, so if one craps out, you're not left high and dry.

    And 9 watts is a little high for me; I'm generally more at between 5 and 7.

    Not sure of the exact differences between the 2.0 and 2.5, except to say "just get the 2.5" (or now, I think, either the 2.5 or the 3.0)

    Thanks to everyone for their replies. It appears that the consensus is a vivi nova works best between 4-8 watts so I ordered some 2.4 ohm heads to tie me over until I figure out what my preferred resistance is. And just so no one is overly concerned.......I ordered two chargers as well. Lol.
