I'm currently at work now so cannot explain as much as I would like.
Edit: I will upload a video later today showing the driver and it's movement.
Anyways I have ordered and received the 1W from XPL. And yes there was some issues. First off they did a terrible packaging the laser. I will get into that more with pictures later today.
Second, the push button switch immediately started to get stuck. I looked down the battery chamber and noticed that while pressing the button the driver would move with a tolerance of about 1/4". I asked about why the driver is moving and should it be that way from factory. The answer I got back was that there must have been something happened during shipping and would like me to send the laser back for repair.
Apparently on the 1w version they do not support the driver thus giving it room to breathe, also move.
Edit: Third: And this could be a pet peeve of mine, but the focus knob, that I believe was added to their non-focusing hosts for 1w+, has ALOT of play, just simply twisting the laser quickly will cause a noticeable lens adjustment that was not intended. I have only about 3 min of use so far so I haven't really been able to give everything a good look.
I'm sorry but I will add more at lunch time. Also the 1w I received mode hops like crazy, definitely NOT tem00
Edit: Good with the bad: Damn is this thing bright!! The picture has a eb@y cheapo along with the 1w lasing except the camera couldn't pick it up. Besides the driver and focus knob issue, the host is very sturdy and rigid. I did a 20second run last night and the host just barely started to get warm to the touch
