Hi all! I am a newbie to this forum, however I started using ecigs 1 1/2 years ago. I started with disposables, and eventually ended up with the Blu Premium Pack. At someone's suggestion, I have been buying juice and just refilling the blu cartridges. This has worked for me, but I wonder if I am missing out on something. I have 2 joyech batteries and the chargers to go with them, so I hate to make any big investments at this point. What would you veteran vapers suggest for me. I vape strictly menthol. Thanks!
