Long-Lasting 650 mAh battery  is a definite pro

 

Magnetic lock to easily snap your cart into place 

 

Over-voltage and short-circuit protection

 

 

 

I thought the NOVA Hush provided a good consistant hit across all ranges. You can adjust the level by using "quick draws" or a button on the bottom. A typical range of voltages from 3.0V- 3.8. 

It's got a nice faux leather feel that is easy to hold on to. All this for only $30. While supplies last!

Stress Tested by the most clumsy user we could find  --  That would be me!  Being dropped numerous times and cracked with a leaky cartridge just doesn't stop this vap battery! IT STILL WORKS!!
