I had the same problem & it started after 6 weeks & got worse & worse till it didn´t work any more.....that´s what gave me the excuse or motivation to spend the money for a Vaporshark rDNA30.
Seems like we are not the only ones this happened to.....
It will be interesting to see if the build quality of the SVD 2 is better.... they can put in a board from Evolv all they want but if the rest of the unit isn´t improved compared to its earlier version....it won´t do much good.
innokin needs to prove themselves & show that they´ve stepped up their game if they want my money in the future.
