To be clear. The VROD is a shower head but is a little different. It will milk your glass just as fast and takes the same number of draws to clear the bowl. If you want to see a VROD video just watch one of the shower head because it is basically the same thing.
That darker ring coil artifact in the bowl of my VROD was caused by my learned shower head draw and the heater coil as you pointed out. I was just pulling a little too hard on this vape. I made very slight adjustments to my draw and it works so close to a shower head that I am very pleased.
I am not ever going back to the shower head.
Sorry no videos my friend. Just too lazy.

You should feel completely comfortable getting the VROD. It is a stellar vape.
