I usually store mine in the drawer but for fruity/menthol juice, I put them in the fridge to refreshen their taste but it may just be a placebo effect.
I'm thinking of dry hits. If you're taking a long hits or chain vaping, try doing a primer pulls every once in a while or when you're tasting that burnt taste

Damn good mod, answering base on my personal opinion. For the price, build and feature; it's a pretty good more at this point in time. Go ahead, make sure you play with temp mode.
