I'll tell ya what, the Drop is a venerable now old RDA. I still have mine on my JMocz series box. I still love that thing, but that's the problem. I've accumulated alotta stuff over the last couple years. I've been seeing things I haven't touched in a while and thought "hey, I haven't used ___________ for a long time, lets pull that back put for a whirl." And then I remember how good it is and I wind up with like 10 or 12 setups in the rotation, I'm sure nobody can relate to that at all.
I love the drop, and could care less about what is new or old. I don't drip that often, so I stick to what I like. I probably have 50 or so RDA's that are "newer", but don't stack up. Kinda makes me think there needs to be a sale there as well.....
I still use a ton of my bottom af RDA's that so many call leakers. They just perform, and only leak if you over drip or over squonk, imho
Mad Hatter comes immediately to mind. Yes you can easily over drip, but if you don't, the thing is just fantastic
I could probably dig out 10 more that fall in the same boat. I am totally at a point with vape gear as if it's new, doesn't mean it is good.
