    Serpent SMM

    Posted by David Grote on Aug 15, 2017

    Fantastic single coil rta. My favorite..am enjoying it more than Augvape Merlin and Serpent mini. Has maybe .2mm more room when mounted on eVic Primo Mini...is almost flush. Came with tri-tool...not merely plain Allen wrench. Lemo 2 drip tip works and looks good. Is my go-to single coil RTA. 2.5mm Clapton (28x36, 8-wrap, spaced, .87ohm) allows smoother airflow than 3mm

    Amazing little RTA!!

    Posted by Lane Carman on Jul 17, 2017

    This RTA is awesome! I wanted something stealthy with good flavor and this thing is just that. Super simple to build on and holds 4ml of eliquid while still maintaining a small and stealthy look. Oh and not to mention not a drop of liquid has leaked from this thing which is common with RTAs as they can be tricky to get wicked properly in my experience. The side air flow on this thing is perfect and offers a slightly restricted airflow compared to other RTAs on the market right now. It's just all around an amazing RTA with excellent build quality and performance. You won't be disappointed if you are looking for a leak free, stealthy, and super flavorful sing coil vape experience. Wotofo and Matt knocked this one out of the park. As always eciggity was a pleasure to do business with and the shipping was quick!!

    Surprisingly Airy

    Posted by GERALD (Ed) ANDREWS on Jul 05, 2017

    After all the talk about "slightly restricted" air flow, I am surprised at how loose the draw is. And NOISY ! ! This thing whistles, or at least swooshes, more than one would expect from a "slightly restricted" air flow. Easy as can be to coil and wick, so it is simple enough to experiment with set ups. I settled on 3.5mm dual core parallel Clapton, 5 wraps, thinning the wick tails with a dental pick before stuffing. This is a cloud chucking flavor machine, no doubt. But why so swooshy? And why is so much of the liquid hidden behind the base/air flow ring? Makes the capacity deceiving. Absolute quality construction with superior quality materials. Excellent flavor, but why no knurling on the top cap? Bottom line....there are better choices, not that this is a bad choice. Still partial to the original single coil Merlin and the single coil Ammit. Those are better choices, in my opinion.

    One of the best single coil tanks!

    Posted by toddm808 on Jun 28, 2017

    Mostly use drippers, but if I do use a tank it's usually a single coil. Figure I'd give it a try... This one is pretty damn good! Everything about it is easy, easy build and easy to wick. I get good flavor and vapor off this RTA and only from a single coil fused clapton build. It's short and still holds about 4ml of eliquid. If you are looking for a single coil RTA this one is worth checking out.

Collaboratively designed by Youtube Reviewer Suck My Mod and WOTOFO, the Serpent SMM 24mm RTA features a unique single coil build deck which is designed to support both forward (leads wrapped over) and reverse (leads wrapped under) coil building. Despite its low profile and compact design, the Serpent SMM RTA has a 4ml tank capacity which is conveniently refillable through its threaded top fill design. The build deck features a 2 post block design with a total of 4 terminals to accommodate forward and reverse built coil configurations. In addition, each post block has 2 airflow slots stacked vertically on top of each other to provide direct side and bottom airflow for maximum flavor.

Please Note: The Blue Serpent SMM is randomly packaged with either a Black Delrin or Ultem 510 Drip Tip.
