It's been years since I upgraded tanks. I love my 7ml protank/Subtank. I suck at building but have a good process for my mini rba plus. All tanks are broke. Anyone know where I can buy replacement glass? Are there any other tanks that are compatible with that RBA? I'm so out of the loop when it comes to buying new Vape gear I just like what I've been using for years and would really appreciate some help
