I ordered a juppi from fasttech Christmas weekend despite my apprehension due to issues with prior Kanger boxes. I love their tanks but haven't been lucky with the mods. Got it in the mail tonight, opened her all up filled it with juice and boom "check atomizer" tried 5 other tanks with the same issue and then tried the juppi tank on other mods and it registers just fine. The tank is actually quite delicious. I took the box apart and all the wiring appears to have a solid connection but then again I don't really know what I'm doing at this point haha. Anyways, it's a great looking mod. I hope I can get Kanger or fasttech to replace it. Does anyone else have one of these? Haven't seen much discussion on here about it. Any suggestions on a home fix for a potential 510 issue with it?
