The mini appears to be a little more efficient then the 350 (I could be wrong) but 120W is wasted on me, I have played around at 80 and tried 120 but found it to hot.
The up/down takes some getting used to, it is not like the DNA where you can just up and down it.
The power, standard/soft/powerful are a nice feature, it helps with the ramp up if you are using heavier gauge wire.
If I had to rate this chip on a scale of 1-10 I would hover around 8, the chip by no means is mini and the up/down is the only draw back. Not a drawback but for design purposes they have very poor data on the chip, got to love evolv and there data sheets
The case is a shapeways print, it is there white strong and flexible, a real dirt magnet. I tore the mod down and am going to cerakote it today.
