Thank you very much! Press-fit bases tend to either loosen, breaking electrical conductivity or leak (if they hold orings and liquids), and atomizers with them suffer prom problems down the line.

My Merlin loses 1ml of liquid through the base overnight for example, and repairing it is not trivial. My Lemo 2s' press-fit bases (I have 5 of them) tend to loosen over time, and any slight bump on the atomizer will slightly separate the two pieces, leading to the positive pin in the center to break connection. Repair requires a plumber's wrench to press the base, nothing to do if you're out and about.
