This rock box 40 I couldn't repair because the connector stuck with the body. I also still can't figure out how to take out the connector and best thing that mod just sleep inside my drawer..haha.. I bought new mod but still looking DNA mod. In Malaysia the price quite expensive for DNA mod because everybody know the DNA chip is the best.
I had a problem with my rock box dna 40. The ohm keep on jumping. I try to change another tank and clean up the connector but result didn't change anything. Sometimes it taste burn but just setup new coil. Anyone experience with this kind of problem?
