Nothing like the feeling of a short circuit in your hand

[JaRod]

So I bought a Sentinel M16 clone, and I liked it so much that I bought the original Grand Vapor M16 and also the Sentinel V4, just to realize that the originals have a nasty design flaw. The center pin, or positive contact is a flat screw, so big that if you use an atty with adjustable center pin and it happens to sit flush with the outer thread it'll short out because the mod's (huge) center pin (positive) and its body (negative) will both touch the 510 thread of your atty. Of course you can use the mod by making sure that the center pin of your atty is protruding beyond the edge of the thread, yet it happened to me not once, not twice but 3 times with an Ithaca atty because the atty's center pin rotates when you are screwing it in in the mod, resulting in a nice shortcut that slightly burned my pinky finger. So I felt like sharing this with you because this mods are not safe, certainly not for a beginner. I've attached a picture of the Sentinel V4 (far right) compared to a Pisces (center) and a Nemesis (Left) so you can see what I mean.

Good catch!! Guess just 'cause it's pretty outside doesn't mean the engineering is done properly..

My Sentinel M16 from FT works just fine.

Will take a look, as I've had no problems.

Yes, once in a while a clone maker will implement a fix for a design problem with the original. This isn't the first example and I'm sure it won't be the last.

I'm glad you only got a scare! It could have been a lot worse, specially since first reaction to something hot is typicaly throw it accross the room or out the window. I wouldn't have expected that from Grand Vapor, but then again, no design is without its flaws.
