Both of my Rivas have stopped working, one about a week ago and now the other about 5 minutes ago. They appear to be fully charged and will light up if I hold down the button but if I put an atomizer on them they just blink like their dead. Anyone else have this happen? Are they just done for or can they be revived? For now I guess Im back to my 808 with adapters so I can still drip.
