Welcome to an awesome new world!! Trust me, this is all too familiar, my friend. I started with (and still use daily in the car etc) the Halo Triton. Halo makes great products and juices plus their tank/battery combos are very well matched and "idiot proof"!
Very soon, I realized how (foolishly) limiting their 808 threading was and went in search of a "standard" 510 threaded device to avoid all the adapters etc. There's a million and 1 options, reviews and opinions out there. I too spent night after night researching what to get, what's the best this or that etc. Do yourself a favor- figure out what features you're looking for (variable wattage in my opinion) and get the very
best device you can afford...
from a reputable dealer!! Do not simply buy "one step up" from the cheapest place you find it (unless they have received great reviews). Reasons: 1.
you will constantly be wanting
"the next best thing" and will waste money if you go one step at a time. Jump up and you'll not have a bunch of paper weights! Most of us have done this.

2. Always, always buy from a dealer with great reviews and customer service even if it costs a little more. Customer service and problem resolution with orders is
paramount...believe me!!! Nothing is worse than spending countless hours researching and "finding the very best deal" and getting burned by one of the
many new dealers and websites that are simply overwhelmed, not knowledgeable or are flat out slack!! There are WAY too many great places to deal with to end up getting hosed because you tried to save $10. Hoping to help you and anyone else avoid the (few) pitfalls that I encountered. 3. Vape and enjoy better everything (smell, taste, health, convenience etc)
