Sorry about PA :-(
There's a 99% probability that the many 2.5's I own will end up being the only Provis I ever do own. I like them THAT much, and stocked up when the fire sales where on. Now that they've landed in low-price land, I'd easily grab more of these, versus the mechs that never did work well for my vape preferences.
At $40 (or less), these things are a steal.
I realize that the others have more features, but I've got plenty of mods with fancy features, yet none I'd say vape better than the most basic-of-basic v2.5's. They'll remain a favorite of mine forever.
TWO thumbs UP.
