I am using it right now!
It is by far the most versatile of my mods, and I own a LOT.
The 3.7 v version doubles as a passthru (and battery charger), so you almost never have to charge the battery. I've had the same battery in there for 3 months now.
Sometimes I toss a 901/kr8 adapter on it for cartomizers, but lately I have been rocking a LR atty with some
tobacco absolute.
Hope you like it as much as I do.
