Zorro passthrough variable voltage 3v to 6v

Update: I am now recommending the Sigelei 100w. Click here to see the first look.
I sold my Duke this weekend on ecf because I find the the display on the zorro is better for to reviewing ejuice. (I don't have the zorro anymore too)
You can read about the Duke click here. 
The Zorro has a voltmeter attached to it.
You can change the voltage from 3v to 6v. I build my atties to  .7 ohm atties but I hear you can build them lower. It is a great device I have not had any problem with it and have used it daily for months. I use a 510 to ego adapter on it so I don't accidentally mess with the threads. The trident v2 is on it. 

You can see a video review I used it by clicking here. 
You can get the Zorro here with a different name.
