the bottom edge feels so sharp, it's really horrible to hold, the display only shows the voltage and amps when you fire, but as it's on the bottom you can't see that anyway, the up down buttons are in my palm, my index finger sits nicely over the air intake on my tank so blocks the airflow. you can't use it in the rain as the water would go straight in the massive holes in the battery cap and down the side of your battery. the grooves in the tube are really uncomfortable, all my tanks either look too short or too tall. Aspire really paid them to design this?
I really hate it...
