I just got my e-Bay iStick. Wow... This is a Cool Mod!
The Fit in my Hand is Unreal. Build seems Good. Buttons are Crisp. I like the way when you Hold Down the + or - that it Cycles on its Own. Ohms are Right on the Money. Screen is Clear and Very Readable. No Rattle Snake. Nice, Smooth Hit.
I would have No Problem Recommending this Unit to Just About Anyone who Doesn't Sub-Ohm. This Mod is a WINNER.
As to Voltage Range? I Can't Verify it. Because without an Atty attached to the Unit, you get a "Check Atomizer" warning. So Probing it with DMM Leads Doesn't Work.
But. For a 2.8 Ohm Clearo, I see a Noticeable Drop in the Hit when I set the Unit to either 3v or 3W than I do when I set it for what I would Normally use it at, 6.5W ~ 7.5W.
Guess will have to wait for Some Techie with all the Scopes and Shunts and Dials to do a Full Electrical Analysis on the Output.
