Well, I grew to like the ijust 2 okay, the flavor improved (think the initial burnt taste stuck around a little bit somehow) but it was a little too airy for me, dried out and irritated my throat sometimes, and the flavor was a bit light. It actually fell out of my purse onto a really hard floor at a hardware store today and the tank shattered and now the battery is not working properly, so I need another backup since I am back down to one device. I am actually going to re-order another subvod/toptank kit, which is the same price as the ijust 2, even though the tank is smaller and the battery doesn't last as long. The vape is a bit warmer in the toptank/subvod and the flavor is a bit richer to me, and I can taste a bit more of the complexity in my liquids.
