Hi. I'm still fairly new to vaping and could use a little help. As of now I am using a Blaze Life Pen. I am planning on upgrading but for now I'm making the best of what I have. I have been using disposable tanks ego style 510 thread. Sometimes they work great but they are inconsistant. One will give you great hits and another of the same brand will give you moderate hits and a few won't give you anything at all. After 3 weeks to a month they get weak and I buy replacements. I am looking to buy a glass tank that you don't have to replace and gives you a great hit. I read reviews on many different tanks and see a lot of them are leakers. Any suggestions for a good tank? Thanks.
