I haven't had it for very long (OK, a few days) but if you're looking for something small, the new Aspire Plato will give you 50W VV/W and TC. No idea how it will wear over time, but out of the box it feels like a solid, well made product. It's got a nice feeling aluminum case, and so far, as a MTL user, really great performance. I've seen it can make nice clouds, especially given its size, but it's not a heavy hitter compared to higher powered mods. Then again, it's only a single battery mod.
Drawbacks are it is a side by side design and limits you to Aspire's
coils. Any of the Nautilus or Triton mini coils will fit, along with a proprietary 0.4 ohm coil made to fit only this box. I know some folks have played around with an RBA for Nautilus and got it to fit, but it's not an "experimenter's" dream. The
tank is a little odd, but easy to fill and clean. And of course, no way to experiment with different
tanks. But it looks and feels great, so if you're thinking of something to carry around, you might want to take a look.
It's not a Provari or Vapor Shark, but it's a lot more affordable and feels like a quality mod that would cost more.
