I can't say enough good things about my little Derringer clone. I've been vaping my face off with it night and day, and can honestly say it just suits me perfectly. I've got it built with a single micro coil of 24g Kanthal A-1, wrapped 7 times around a 2 mm screwdriver and clocking in at around .6 ohms. The flavor is insane. Airflow is just right, wide open in single coil mode. The vape is very warm and wet, and spitback is minimal. When I do get it, which is rare, it's only a little and hardly noticeable. Not sure why so many are complaining about spitback with this atty.
The only problem I've had is an issue with the top o-ring. There are two o-rings on the build deck: the top one is for the inner barrel, and the bottom one is for the outer barrel. While snapping the inner barrel onto the top o-ring I pinched it, and over time it started tearing apart. So I grabbed a replacement from the little bag that came with the rda and slapped it in there. That one fit worse than the first one, and it was torn and shredding in no time.
So I pulled out my collection of o-rings and tossed them on the table like some high-tech oracle. I immediately found a ring with the same thickness but smaller diameter. I put it into the groove on the Derringer and grabbed the inner barrel. I licked my finger and ran it around the o-ring, then slid the barrel down. There was a satisfying, dull snap as the barrel seemed to lock into place. Exactly where it should be. Clearly, the manufacturer of this clone forgot that the upper o-ring needs to be a few mm's smaller than the lower one. The problem is, that was the only one of its size in my collection, so it's not a common o-ring. Hopefully this one will last a good long time.
