So I am new to forum, but have been vaping several months. Would like some advice re: EVOD clearomizers. Was reading everywhere how wonderful they were and recommendations both here and other sites. Well, bought my first one and it immediately leaked every where. So, spent a little more money and bought a second one, thinking okay one is slightly defective. It also leaked. Then I tried a G 50. It leaked. Think I am done with bottom fill, bottom coil. Have watched several You Tube videos and have tried everything I can think of short of totally rebuilding and it is not worth all that except I do have almost $50 bucks invested. Have tried screwing real tight, blowing them out, screwing tight, tight, cleaning threads on both batt and clearo. So what does one do to use these bottom coil things?
