Welcome Cass
You've inherited a fine piece of equiptment. Reliable. I've had the complete opposite experience w/ Drew then you had "elsewhere". He went too far overboard to compensate me and I think you'll happy all around. He's a great guy to deal with and makes the best tasting juice I've found. & FAST on shipping.
The Xhaler is big & solid, but not heavy.. (compared to our itty bitty)
The enhanced flavor is a nice change w/ the big one (though I do like my tiny ones for public)
They're right about the batteries. These are the only ones I have that have their own charger right now... seperate from the multi, but that is a good thing. For a big batt mod, the LifePO4 is a much safer way to go anyway. If it's too much & you want to drop back to 3.7 the dummy spacer battery is very inexpensive.
Kick back, relax... and enjoy. It won't be long. I vividly remember my first WOW on the Xhaler. heehee.
I agree 100%
