Here is a fantastic pre-order Sigelei deal. This is by far the lowest I have seen for the Stainless model. You can get them in Polished Stainless, Brushed Stainless, or even Black Chromed Aluminum.
THE HARD COPY:
The ZMAX APV by Sigelei is sleek, powerful, and RELIABLE! Full featured and extremely well built, Voltage or Wattage can be tuned between 3-6 volts or 3-15 watts respectively. The ZMAX uses a single 18650 or two 18350 IMR batteries with the included extender cap. Additionally, it will check the atomizer / cartomizer resistance and battery voltage as well!
The ZMAX has a menu item which enables you to switch between RMS and mean value voltage monitoring. The RMS mode is more accurate because it samples the output voltage repeatedly while it is powering an atomizer or cartomizer.
This unit has a 4 AMP output!!! We are providing this kit as a dual 18350 system because it provides more power in this configuration than a single 18650 does. However, the single 18650 mode is fine for most people running less than 12 watts, and it lasts a bit longer.
This version has a non-lighted clear button and very easy to read 2 line OLED display that can be turned off. It has the native eGo/510 connection so it will run the Vision eGo Clearomizers, CE4/5 and other eGo devices without adapters.
