Sorry Podo, This is my first attempt at a review.
It doesn't capture the true quality and workmanship of Sanwu's lasers.

Very nice laser, but could you please use external image hosting sites? Personally I'm partial to Photobucket, but use whatever you like and use IMG links to link your photos directly in your posts. You can do same with videos for youtube, that way you can link whatever size and count of images you like

From the Sanwu website...

Laser modes/ Diode / battery Protections:


Multi operation modes: Safety Mode <10mw, half power, Strobe, Full Power and SOS mod


Change Mode:
Half-tap to switch between mode.


Electronic lock:
To prevent unauthorized use, half-tap the tailcap 3 times within the first 3 seconds and wait for another 3 second after imput. Then it will lock as safety mode(<10mw)


Unlock:
Just repeat the same process but half-tap five times instead

Does it have a spring for one of the battery contacts? I'm getting one of these and I'm hoping I got the right batteries if it is fixed contacts (I got unprotected button-top Efest).

Yes on the tail cap. Its a spring loaded button. Second pic. The tail as are by the batteries. Look on the site it says what type of battery you will need. There should be enough spring travel to accommodate button top batteries.
