Went through a bunch of mini's. Got a rough stack maxi from
mad vapes. Then got 3 more. Now my wife and I both use them. We carry spare cart's and batt's pre-assembled and redy to
vape. I am using kydex holster material to encase the spare units till needed. With 18650 batt we get 2.5 days of good
vape and 4 carts each. I started to get a ego, but I skipped the middle. I am looking at the Darwin next, at least a pass through model. Then I can charge and vape without the wait.
