Today is day four with the GX2/4 and really lovin it. Not just being able to vary wattage but also soft-normal-hard for how fast the coil heats can make a huge difference.
While have a Stick V8 for backup wouldn't want to have to go back to it. So ordered another GX2/4 kit, this one in blue, for $54.07 shipped.

Not a US vendor but don't need it fast so went for the lowest price possible.
The TFV12 Cloud Beast King atty I ordered to play with arrived yesterday. OMG I ain't ready for that sucker yet if ever!

I'll stick with Big Baby Beast and the T8 0.15 ohm coils for now.
The one hit is same as I've read on a few review: the battery latch can be a bit finicky. Oh and agree the finish seems like it will be much more durable than anodized like the Alien.
