This vaporizer had no visible screws and a very interesting hidden way to open it.
The problem I had with my vaporizer was that it melted the top connector piece and we had no clue how to open it to fix it.
Step 1 is removing the magnetic plates
Step 2 heat the side with a blow dryer enough to melt the adhesive adhering the metal plate down.
Step 3 wedge something thin under putter layer to pry metal plate off
Step 4 remove metal plate heat adhesive again if needed.
Step 5 remove screws
Step 6 take outter cover off of vaporizer
