When I put my Sapor rda on my Wismec predator, it says "atomizer not found." If I screw the thing that connects to the 510 connection then it says "atomizer short." If I'm lucky then the rda will work for 2 or 3 hits when it's the thing on the bottom is screwed in perfectly. The rda works fine for other devices. What is the problem?
