OK, I've been on the Joye 510 a few days shy of a month & I like it. I don't love it but I like it.My take so far:
A: They are juice hogs & you will be topping off often if you vape heavy

B: The cart will melt if you don't line them up &/or keep them topped off

C: The carts w/straw mod wick better & longer than standard(done rite)

D: The carts wick & fill better if you take just a tad of the filler out

E: It takes about half a battery to get the funky taste out of a new atty8-o
F: The teabag thing works pretty good, but is a pain in the ...

G: The auto batts are worthless in the wind & while mowing or jamming

H: I like the whistle tips better than the round

I: My tongue is not brown anymore

J: There is a wealth of info here

K: Kreel is kinda mean to noobs, IMHO

L: Carry 2 complete ecigs,cuz change carts will driving is dangerous8-o
M: Dripping or topping off while driving is frowned on
After all that's been covered on the 510, being a juice hot & attys running hot. I have to wonder about this Prodigy & making the 510 adapter.
Seems to me that extra power would be really hard on the attys & you'd be topping off every other drag.
