+1 to all the Thumbs Up above.
Simple, Resilient, Cheap comparatively, replaceable Battery, Performs well even with RDAs, Great little Outside/Yard Work Knock-Around Device or Bedside Vape. Actually pretty impressed with the little Devil.
Mated to a Subtank Mini using the .5 OCC Coil set to 25W (30 on thicker Juices) it is really pretty satisfying.
Like it much more than I thought I would when chose it to replace an old CoolFire 1 and MegaTank Rig I used forever as my Outside Vaper.
Thinking about a SubBox Starter now.
Wasn't aware of the Top Pin Isolator Issue outed in earlier Post. Be watching for that.
So far no issues with the floating Pin Connector.
If you can swing the $55, go with the SubBox Starter Kit. Comes with all you need except a Charger and Juice. An overall great Device and awesome Value for the buck which should do all you need or want now and well into your Vaping Future.
*Update... The Price for the Sub Box/Sub Tank Mini Starter Kit is now $79.99
Supposedly, Kanger has set a minimum Retail Price and holding contracted Retailers to that set Price. However, it is still a great Value IMO. The Sub Box has an OLED Screen and goes from 7W to 50W in .1 increments and not just 40W at preset levels as the K Box does. Also has a mini-USB Charger built in and offers Pass-through Operation. Supports down to .3 ohm builds as well.
Given all that,,, skip the K Box and get the Sub Box. A No-Brainer.
I know this as I just purchased one from Mt Baker. They have both the Black and the White Kits in stock and throw in a 15ml Bottle of their Juice of your choice to sweeten the Deal.
