You'll need the 901 tip to run KR808 carts and a 510 tip (adaptor) for 510 atty's.
Get a least 2 sets of
batteries (4 RCR123A's) to start as well.
Then while you are waiting for it to arrive go to the hardware store and get some noalox and watch Drew's videos on the Xhaler maintenance sticky. That way when it arrives you can charge the first set of
batteries and set up the switch before
vape heaven!
