Actually what I have learned is, istick 50 watt clones were catching on fire. I could be mixe dup with the actual authentic versions. Listen I just want to vape without catching on fire. I hear mech mods unregulated devices can ignite just from your keys in your pockets touching them. I'm far from a Government official. When I see people's devices catching on fire it makes me think maybe it can happen to me. The vape community doesn't buy my ..... If i have an opinion and think something's unsafe I'm stating it. Vaping is great but I'm not drooling over it. Nor do I buy every .......n thing that comes out because honestly every mod that comes out looks the same as the last mod.
I understand your concerns...........and share in them. However I use Knowledge, not fear to drive my choices and safe practices.
I Have highlighted Misinformation in your post, which could be adding undue stress.
Keys do not and cannot make Metal Tubes explode.
Keys could possibly depress an unlocked Mods switch, allowing it to continuously fire.
Keys could Short out an unprotected battery carried in a pocket.
Understanding is 90% of the battle.
Did a little Digging on iStick 50 Fire.
Found 1 Youtube Video and a Crap load of Riddit Followers Slamming the iStick over it.
Not at all unlike the Fiasco over a Small Batch of Cloupor Mini 30w that had issues a while back.
I like to refer to this as Chicken little Syndrome.
There is and will always be a percentage of product failures in mass production. Something which has never changed and likely never will. They are the unpredictable minuscule few that get by QC before rearing their ugly head. While we would prefer none Explode or Catch fire, there is almost no way to make that guarantee with a Battery powered Electronic device of any type.
However, hearing about = passing along the Rumor
Looking into = Educating oneself on product Quality
Best of luck in your Vaping journey and Choices in life.
