So I am new to vaping. (10 days in.) I got two Kanger EVOD tanks from a local B&M. They worked great. Went to a different B&M and bought 3 more. They have been awful. Pretty sure that they are knock offs. Bought heads as well. Now 2 of the 3 are leaking. How does everyone here ensure they are not getting knock off equipment?
Thanks,
Thanks,
