They stick well to plastic under the dashboard and to galvanized metal on my trailer. Good adhesive. I place this in my car so it becomes a cheapman's lowjack system for when my car gets stolen. It works 100% better then the * tile for android.
Bought two. Drilled a hole and cut wires to splice into new outlets. Fit into my existing console without a problem. It fit tight as i had to screw it in with the threads, but fit without mods.
