I don't have one yet, I think they are good looking, but I don't like acrylic mods... you sneeze the wrong way, its falls on a cloud of feathers and they crack
or just my luck in the past with acrylics.
There is only 4 points of contacts with the Atom
1. Atomizer
2. Battery
3. 2 screws at top
4. 1 screw at bottom
I'd take the 2 screws up top off, clean the threads of the screws and clean the contact faces,do the same for the firing bar
The bottom contact shouldn't make a difference clean or dirty since it only screws into ultem
