Its ok. Hits hard and the fire button is spot on, feels nice in the hand...
Thats the good.
Now the bad.
510 connection is not adjustable nor is it floating. sucky gaps with lots of rda's or tanks. You also have to tighten things on so hard to get them to fire.
Little bit of battery rattle
cant see the voltage unless you take the side off, and the side doesn't come off with all sizes of attys attached.
The two little magnets holding the side plate on do so pretty badly, there is rattle and a not complete feeling.
Even thought there are bad points I still really like the mod, using it now, forgetting all the negs, it hits like a train.
