Nail polish and water? It's almost like you wanted to destroy things!

Seriously though that's brutal.
I did link my review here (with pictures!) as
@Tpat591 touched on. I haven't had a dry or harsh hot on the eGrip II yet and I even vaped it past where I couldn't see any liquid. It's not as tight as my ego one but still very MTL worthy.
The adapter works really well for other
tanks too, just be careful not to overtighten external
tanks. I did once to see how hard it would be to get apart and it's not easy to grip the adapter as it's smooth. Other than that it feels solid with any tank on it, no wobble and things fit flush.
Hope jet lag treats you well! Let me know if you have more questions
