I had an accident with my Vamo last night using a Vision rebuildable clearomizer. The Vision clearomizer fits the Vamo just fine and works great. But, when I unscrewed it to remove it from the Vamo, instead of unscrewing from the Vamo the clearomizer unscrewed at the diassemble point. The clearomizer tube came off and my e-liquid spilled out. The base of the clearomizer remained on the 510 connection. It did not hurt the Vamo but I had to use pliers on the clearomizer center post to unscrew the base of the clearomizer from the Vamo.
When the clearomizer is on the Vamo, the threads where the clearomizer comes apart are down inside the end of the Vamo. It is hard to tell when removing the clearomizer if it is unscrewing at the 510 threads or if the tube portion of the clearomizer is unscrewing from the base of the clearomizer.
Since the accident I have been careful to screw the clearomizer together firmly and to not screw the 510 thread too tight. By doing this I hope that the clearomizer will stay together when removing it from my Vamo. See picture below.
