sorry to hear that yewrev, yes, they will send you more stems if you contact their customer service, (they asked me for a pic which i havent gotten around to yet) that said though, i dont know anyone yet to get replacement stems that worked... they were still working thru some bad stock they had, (for some reason i want to say some 10000 stems were faulty) although stealth1 has a new unit and hasnt mentioned a bad stem yet...which may indicate theyve used up all the bad shit. i ended up just buying the replacements when mine melted...(i know it sucked having to buy them, but i was too impatient to wait for shit to come from ireland....) i bought my stems from warehouse goods on ebay, (look under ebay stores...) it was about $15 including the shipping... but, the stems havent failed yet, so, i guess its all good....
ok willieR, i took the vape4health squirt test.... vector vs. yellow can shit, (neon) vs. near empty can of vector squirted on a mirror.... all left some residue... neon by far the worse, leaving the equivalent of a dirty finger print smudge on the glass, to assign it a number for comparison, with 1 being like milk and 10 like water, i would give the neon (yellow can shit) a 3...the vector full can left a ghost of a pattern, but no where near the neon, i would give it about an 7-8.... and interestingly enough, the almost empty vector was just as opaque as the neon...a 3 on my scale.... which, (although not extremely scientific,) definitely makes a strong case for my previous post about my suspicion of impurities being present at the end of a butane can... regardless of brand...(i had noticed this after my iolite started acting up toward the end of the butane can) hope some other folks try it and post their findings.... :/ also, does anyone know how to post pictures or video?
