Left is Lost Vape's Drone regulated squonker from
@MannyScoot. It keeps doing well for a regulated device, touch wood thrice. Capping it is a staunch favorite, Advken's Gorge with a derlin heat displacing drip tip. It's running a .50 Ω coil, 3 mm ID of 26 ga Kanthal round wire, Cotton Bacon Prime for wick. Using pure unflavored max VG juice at 18 mg per ml nicotine strength. The vaping experience on it is quite nice.
Right, as facing you looking at them, is the Requiem mod from its kit by Vapepoo. The Requiem RDA is just a wee bit too hot to vape for my tastes. I have tried taller drip tips. May need to rebuild it. For now, it has a Wasp Nano on it running ~.30 Ω coil, again 3 mm ID 26 ga Kanthal. Getting ready to slap a Bombertech Firefly on it, also from
@MannyScoot. There does not seem much difference from a Wasp, yet there is a subtle difference. A Firefly RDA draws air from below the coil, whilst the Wasp from the sides of the coil. Vaping exp. on the Requiem mechanical mod has been a joyful treat. In it I'm using some "junk juice".
