Ok, so i have just started vaping on this mod and i gotta say, DAMN I LOVE IT!!! To all of you who have seen reviews on youtube about this mod, they are all outdated. Don't ask me why, maybe call me crazy, but my B.A.M is not exactly the (Big ... Mod) that you see in any of the videos anymore. All the vids i've seen on the BAM show this huge beast of a monster you could def beat someone to death with. This is not the case with mine that i just received in the mail yesterday. I do not know if i have a ver.2 or maybe a ver.3?, but this one that i have(in red) does not "look" any bigger than the Silver Bullet(I do not own a SB). For a good size comparison, I do own a Bombshell Stinger, which is actually not a very big mod imho. This B.A.M is seriously no bigger than the Stinger(I would dare to even say its shorter). Compared to the original BAM, this one is also a LOT more slender. This thing grips in your hand like a really comfortable fist pack or something.Still takes a kick and all the same sized batteries 18490-26650. I will post the picture of My BAM next to the Stinger when i get my Stinger back. For now i will post a Pic of it with/next to a 30ml Bottle of Halo Juice which a lot of you will be more familiar with.
