Hard hitting, looks amazing, what more do you need to know? I am already considering buying a second one
I am little dissapointed in two things. Metal contact on the bottom is too weak and requires constant bending to make the batteries less wobbly inside and keep good connection. Second bigger issue would be center 510 pin is too deep and requires also constant adjusting with screwdriver. Sometimes even to that point that whole pin looses so much that it eventually falls out. It could be done as spring loaded center pin.
great little powerhouse can't fault it
Great mod chucks clouds great service from
Not much to say apart from it's amazing, 21700 series power in a pocket friendly form!
