Tesla Review: (Jumping the gun as it is listed as a future possible ALPHA)
Pictures - IMGUR Album
Ok I know I posted pics up earlier as kind of a teaser. I have used the device on and off for about a week and a half. This thing is pretty awesome. The OLED is nice very easy to read and use. Changing Voltages / Wattage is also very easy as well. Hits pretty close to my provari when I set the same voltages as well. The center pin is on a spring so breaking this mod is going to be pretty tough at least at the connector.
So going over the menu it is pretty simple. Hold + for 8 Seconds... (8 seconds should be shorter...) Have 3 options. Use + to change beween and then - to select. You can change Voltage or Wattage output, LCD Display when Firing and then the last option LCD on or off when firing. Out of the menu Holding + will show OHM of the Attached device while holding - will show Voltage Remaining. Pretty easy stuff.
Build quality is a mixed bag for me. The device is no doubt solid, the 3x vents that go down the side are kinda overkill and I think if you were to run it over without a battery in it then it could crush or break as now there are 3 legs instead of a solid tube. They do flex with a lot of pressure but barely and it takes a lot to do it. The cap is also vented at the bottom. No real "quality" issues just more precautions. This thing is MASSIVE compared to all the tube mods I have so SIZE is something to consider with this mod.
As far as Cons, So far I really don't have any. I love the feel of it even though it is pretty big, It doesn't really leave the house so no real travel issues. All in all this thing is pretty awesome and I recommend it for GV / Alpha Testing
Oh Yeah Edit:

How it vapes.... With cartomizers I used on my ProVari and then the Tesla it was pretty close, Maybe just a bit weaker but hardly noticeable. Ran Vivi novas with no problem and got similar vapor production to my ProVari as well. The floating spring pin is pretty awesome as you can fully torque and no worrys of breaking the device.
