Just to get the ball rolling on this, I have had the E-vic since the day after Christmas and I just have to say that it is Amazing.
The device comes with a 2600 mah 18650 battery. This battery lasts me two days when vaping 300+ puffs a day at 7.6watts. (joyetech just came out with a 3400 mah battery, tempted to get this)
What really stands out with this device is that it pretty much has a mini computer, you can set your personal info in it, time and date, records how many puffs you do, what ohms, Voltage, wattage used. all this info can then be uploaded to your computer.
While this info is not NEEDED I love it just because... I like seeing how much I used it so far today, or since I bought it (10820 puffs puffed so far)
This device is a VV/VW, with VW being what I prefer because if I change atties from a 4 ohm one to a 1.8 ohm one I don't need to worry about knocking down the voltage, the device automatically knocks it down so I am still vaping at my 7.6 watt level
The software is upgradable, currently at 1.2, which was a nice upgrade because it gives you an option as to what is displayed on the main screen, I just updated it today so have not dived into all the changes yet, This is the only e-cig I know that you can update the device
Only a few down sides that I can see people having is:
Heavy and bulky, But this is True with all 18650 devices
Text on screen is smaller than most, which I don't mind personally, I can see it perfectly well and they put more info on the screen than just the Voltage/wattage setting that other devices do
button is on opposite side of screen instead of under the screen. Again I don't mind, but can see that it may throw some people off if they are used to the button being below screen.
