Congrats on your new Reo I just got my reo in the mail 2 weeks ago and I can tell you that you are going to enjoy it. I went crazy and ordered a bunch of different attys and cartos but the thing I have been using the most is the 1.7 shorty cartos. They are a great vape and very cheap in price about $1.49 at avid vapor they are a pretty nice back up too. You can't go wrong with any bottom fed lr atty 306 or 510. I find the 1.5 ohm 306 work best for me, but it is all about experiencing it your self. enjoy your new vape!
Ps. I only use the recommended AW IMR 18490 batt because I am pretty sure the
device is designed to work best with them

. Nothing better then a safe battery in your
mod.
