No problem If it makes you happy, then all is well! Wasn't calling you out or anything..
It's just not advice I would recommend to new folks who plan on having a lot of flavors which seems to be occurring a bit more frequently as of late (watching the "order threads"; Good Deals, RF SC, vape mail).
If you only have 30-50 flavors, and/or use them frequently, then plastic will suffice for a few months.
But if you end up with 100 flavors (or more) then glass becomes important.
The strongest flavors I've had (TFA Kona coffee, any MF, etc) would only need a couple months tops before the plastic would be permeated with the scent of that flavor. At which point leeching has occurred.
It all depends on what you're ordering, and how frequently you use it, but some (Kona coffee for example) require glass from day 1 IMO.
Best rule of thumb I would offer to someone new would be: If you use a flavor at 2% or less (single flavor) it should be in glass.
