I have a Innokin isub apex tank. Even with a brand new coil, it doesn't want to vape, it has terrible vapor production. And some times it won't vape at all and I can't get a draw off it. Also it gets really hot. I have an aspire atlantis also. I hate this tank also. It leaks like crazy and kills my batter. I use coolfire and joytech cuboid as my devices to vape from. Please what is a good sub ohm tank that doesn't get too hot or leaks. I just orderded a super tank mini by tobeko. I really like the old school tank aspire mv5 and how it vapes. is there a sub ohm tank similar to this? Do you think the super tank mini by tobeko will work for me?
