It fits perfectly in the hand. It has a nice satin finish. It has a decent heft, but it's not heavy. There is a nice chrome/stainless ring around the fairly deep catch cup. The button is firm but still easy to push. You can set the button to light up or not. The button is not clicky. It has a nice on or off feel about it.
The display takes very little time to figure out. The manual is in a PDF on the ProVape site. I looked at it maybe twice in three weeks. Once you know the abbreviations, you can just push the button until the correct menu is pulled up. It checks the atty/carto ohms, battery level, voltage up/down, turn display on/off, turn power on/off. It is really easy to use...I was almost disappointed that it wasn't more complicated.
