Hey guys, technically new to vaping. Quit smoking since June and was using the V2 pens until today. I was annoyed constantly buying their cartridges and felt I needed something stronger - heard great reviews about this franchise (Avail). They were awesome and very nice and helpful. Leaving I felt I had an idea what to get.... So I go to my nearest Vape Store. Cool people and very friendly, but definitely made a quick (EXPENSIVE) buck off me. Suggested to me (after explaining I'm new, but tired of disposables and cartridge pens) to buy the Kanger KBOX 70 MOD with an Amigo Riptide Top Fill tank. Now I love the Kanger MOD but the Tank's mouth piece is too wide and pulls way too hard while leaking sometimes (adjusted the air valve too). Not only that I went online for tweaking recommendations, and came to realize I paid $180 for this where online I could of paid $80 max!! I am so ...... at myself for not researching better but damn! Recommendations? Am I to be intense like I'm at a car dealership for Vape Stops? I thought consumers licensed with the SEC have more strict retail pricing unlike EBay or Craiglist?! Thanks all, yes I'm a complete dope paying that kind of money for something I wasn't certain with.
