Atmizoo Guppy 16340 Mechanical Mod.  Barely used condition.  Check out my other listings for this sort of product clearance.

From the manufacturer:

Description

The Guppy is a unique 16340 mech mod, made to be robust and simple. Picking up where the Roller and Dingo left off, the Guppy is a lighter but sturdier top-side-firing device which is based on a simple uni-tube design. With its refined, sturdy switch and absolute minimum number of body parts to fiddle with, the Guppy is a hassle-free, pocket-size mech mod.

Designed to bring out the most of high-drain, low-internal-resistance 16340 batteries, the Guppy is one of the tiniest fully mechanical mods with a side-mounted switch. Very close to 18350s in absolute performance, 16340 batteries are ideal for use with 510d-type cartomizers and traditional wick-wire rebuildable atomizers, including 510d-style rebuildables. Usable with resistances above 1.0 Ohm, low-internal-resistance 16340 batteries can power approximately 1.0-1.5ml of hard, good hits. Small enough to fit in pockets, multiple 16340 batteries can be carried around with ease. And as battery chemistries improve, new 16340 cells may soon become usable with sub-ohm resistances, which means that the Guppy is not just a tiny, but also a future-proof mech mod.

Paired with the Bayou, our innovative same-diameter 510d-type tank, the Guppy makes one of the most complete, compact, identifiable kits for vaping a 510d carto or 510d-style rebuildable atomizer.

The simplicity, ease-of-use and performance of the Guppy compared to the Roller and Dingo comes with a style that departs from its predecessors’ bare lines. The Guppy has a slightly more aggressive, naturally flowing form which is still minimal and ergonomic, in line with its unique character.
