Both black and silver are used daily, and I have no issues with them. Both are built to 0.12 ohm with staggered ss316L coils (36 over 26) and wicked with Muji.
Flavor is excellent, wicking is super simple (as mentioned previously).
The black one tends to sweat a little juice around the airflow, and the silver one is bone dry.
I never tried either one with the plastic bubble. Using Ultem on the black, and glass on the silver.
I’m definitely getting an original when they are re-released
