It's really simple stuff that I need to work out. It leaks regularly... especially when the tank is low. I wicked it loosely though so that may have been the problem. It also spit back hot liquid after the leaks.
I wicked it tighter and now it isn't leaking, but it's not wicking or tasting nearly as good as before. It also jump into temp protect kinda often now. I'll try other wicking methods.
The top cap get stuck after I tighten it. It's too slick... it needs something to grip.
