Hi vapers. So, I've got a problem. I have a Hana mini clone for about 2weeks now and I've used a 1.2coil on there without an issue. Last night a fellow Vaper tried a 0.7 ohm coil (which should be perfectly fine with the hana) and after 2 hits the device read "too hot". He then built a 1.6ohm coil, and resulted in the same "too hot" issue. Any help on what this could be? Thanks in advance.
