I picked one up.. .nice unit. Though, and I was hoping someone had it... Once I fully charge it, it will never show a full 4 bars... tops out at 3 even though the 4th does blink when its charging up (so its not a messed up LCD cell or anything).
I wouldn't call it light and flimsy though... maybe compared to the big battery
mods, but still fairly hefty in the hand.
