The mod works nice enough, and it sure is rugged. The V2 version fixed all the earlier problems (firebutton sticking and not turning on after standby). I would think all the current stock on these would be the V2 version. It only really has a couple negatives, the biggest issue being battery runtime, as it only gets half the runtime of any of my other mods. It must have a high idle current even when in standby, and using stealth mode to shut off the screen doesnt give any improvement. The other is the battery tube... button-top batteries wont work all that well, the battery cap ends up catching only a couple threads. Also batteries that have a double wrap, like a colored wrap covered with a clear wrap wont fit in it without sticking. I got one stuck and ended up using a magnet to get it back out. Single-wrapped flat tops work fine. I still enjoy using this mod for out and about, and you cant beat the current price.
