Have mine in hand. Been vaping on it for about 2 hours.
Okay, first the skinny.
This is exactly like the Mini 30 on the outside, except they figured out what BLACK is and mine has a Goats head on it. Bezel is Bklack not Chrome.
Came well packaged, just like the Mini 30w.
Even had Mini 30w instructions in the Box. Had to do a double take and make sure I hadn't been ripped.
Function:
Same 5 Memory slots
7w - 70w - SORT OF
No PWM or DC-DC selection
No Mobil................that I have found yet
Press up/down together - MOD LOCKS - will not fire < would have made more since to lock the preset to prevent accidentally switching>
Power and UP simply shows the Memory Slot
Power and Down starts dropping Wattage
Basically - You get more power and less features for 40% more money -
Performance - The mini 2 rips the mini30w a new one at 30 watts.
Ohms seem to read correctly - Even though they stayed with single place reading. .5 not .56 grrrrr
With a Dark Horse on top at 3ohms this thing Billows at 40w, clouds get THICK and Heavy at 50w
You do not want to accidentally hit a Tank set up for 30w at 50w

Instant Char Broil
Compared the mini 2 to the Cloupor mini at 30w since it hits harder than the IPV Mini. Cloupor Never stood a chance.
Tested a Kayfun at 5 watts - Same as the 30w in DC-DC mode, hitting around 12w-13w
Final thoughts
I purchased this to fire some of my higher end design RDA's and my Orchids. In this respect this is a win. Does exactly what (I) need it to.For heavier hitters I say, for the price, go for it.
For the casual Vapor - I would recommend sticking with the 30w for its flexibility.
