Now as for learning about these crazy things which cost an arm and a leg plus your first born I am a Rookie so if you want...take pity on an old Stoner(I bought the first issue of High Times at the Headshop when it first came out))and please I humbly ask y'all for advise and education.....
First off, howdy! Welcome to the forum and all the fun. Good call on the MFLB, but perhaps not the best first vape ever made. Lots of us more experienced gents (and ladies) around, MMJ tends to collect us somewhat.
Don't stress on the cost of gear. Consider that conversion to vaping is a HUGE savings in your weed bill. Guys generally report 1/2 to 1/4 their prior consumption, probably averaging 1/3? Honest. What used to last a week now lasts most of a month. It doesn't take too many months of such savings to justify some pretty high ticket vapes.
And the health benefits, starting a week or two after swearing off blazing for good, are also well received by most and many of us look forward to living longer because of it. Your call there.
I'd probably recommend a unit like the Solo as a first vape. Much easier to use and get consistent results with. Better for learning vaping as opposed to learning how to use a specific vape. Consider it, $160, excellent following and customer support.
WRT the box there are a few things to keep in mind. Keep your batteries freshly charged, your herb fine ground and very well cured. Don't fill over the rails, draw slowly and shake, shake, shake between hits.
You really do need to swear of blazing. Seriously. No cheating at all. At the start your mind links the crap in smoke to getting off, you actually crave that BS! Want to stick your silly face in the camp fire......
Most of us took a week or two to break the connection. You have to get seriously blasted a time or two without focusing on smoke, big clouds, or any of that smoking related stuff. This is different. This is better. Much better. A month or two later and smoking is once again just as repulsive as it was in 1970. Remember how your body begged you to not start another coughing fit? This is how.........
Take it out and play with it, you'll get the hang of it. We did.....
