've noticed a problem with my Riva 510 batteries and a couple of the atties I bought from you guys two 1/2 weeks or so ago. I ordered an SE Steel Riva kit. I get a blinking blue light (three times) whenever I go to use my unit. One of the batteries doesn't even seem to charge when I plug it into the charger. No blinking light, and the light is always green. It only blinks when I have an atty attached, it doesn't matter if I switch atomizers, like the 2nd battery in the kit. No atty attached, no light when pressing the button. When an atty is attached, the light blinks three times whenever I go to use it. I've also noticed that unscrewing atties on the battery in question, also causes the light to blink three times. Again, no atty attached, and button is pressed = no light. When an atty is attached = light blinks three times. When plugged into the charger, no blinking light, and no charge taking place. The charger works fine for the other battery, so I don't think it's the charger. The second battery also does this with two of the four atomizers I have from you guys, but it appears to charge and work with the other two atomizers. Is there something I can do? Is the device screwed? Also an update, this appears to be happening to the other battery as well! Now I have no way to vape, and I'm starting to panic. Any suggestions? I've tried cleaning the threading, etc, but to no avail.
