This little
mod is interesting. Only has
three voltage setting though (3.2 V, 3.4 V and bypass) Super simple design.
That Helix
mod was also sold by several US vendors as part of a kit (Ejuices and 1 or 2 other vendors had them) for much less than the FT price for
just the mod. A friend and I each bought several of them in Black, Orange, and Turquoise, but no White. She loves it as an out-and-about, lightweight, pretty discrete mod. I haven't used any of mine yet though.
It came with a GeekVape Lumi tank (disposable) in a Kit. IIRC, we paid $11 for the first ones we got on Sale. Then we found more later for $8, but we used a coupon code then, too, so they came out to be even less than that.
