I like to think I'm a pretty experienced vaporist, but I've made some pretty boneheaded mistakes lately that would speak otherwise...
-- not packing the Ascent tightly (conduction vape) until told I was using it wrong with a loose pack.
-- throwing some honey soaked cotton in the Sublimator. Cotton doesn't like conduction!
-- never using the LSV cranked way up with a high draw speed after having an SSV for years. It's now the only way I use it.
-- never trying the dab method with my Cloud. Although that did kill it, so maybe that was a good thing.
There is always something to learn!
