I'm using the istick pico with an mxjo 3000mah 35A and an melo 3 mini tank with the triton .3 coil head at 60w and it barely even works for some reason. Im using 70/30 juice so it should be working really well. The coil is rated from 45w to 55w so I don't know why it doesn't work well. I barely get any vapor. All the connections are tight and well. Any tips?
