I have been reading up on vapes and can't figure out a good portable vaporizer for me. I was originally looking at the essential oils glass tank g-pen but I dont want to buy a rebranded e-cig when I can order a ego-w and save money. I am looking for a portable vape that: •doesn't require mixing wax with glycerine •can vape kief would be a great bonus •battery life isn't to important but I don't want it to die after a few hits •a vape that doesn't break often or is cheap to repair. "I forgot the pen but to fix it all you have to do is replace a coil most Of the time"
