I bought a protank from my local brick & mortar, no idea what model. Anyway, it worked great, just like my eVod except it tasted better actually. So, I got the tank Friday, it's Sunday now. I woke up and looked at my SID with the pro tank full of juice, about an hour later, after not touching it for 14 hours, half the juice was suddenly gone so I removed the protank and saw my juice collecting in my SID. I quickly went to the bathroom and put what was in my SID back n the tank, reattached it and tried to vape but it had juice in the center hole so I turned it upside down to blow the juice out. Ended up ALL the juice came out and I finally realized somehow the top chrome piece was 3/4's detached from the tank. I want to hope maybe I bought a knockoff and can order one off the net that works but Idk. Has this happened to anyone else with a true name brand Kanger Protank? Has this happened to anyone with a knockoff? Input needed plz cuz I absolutely LOVED the flavor and want to order a new one now if it's going to work. Also, anyone know anything about the dual single coil tanks? The dual coil tank with two single coils instead of one dual coil.
