  • Hello man, I received one SDLaser 303 today.
    But it don't work, only one time it turn on for 1 millisecond.
    I put the battery reversed, this is no problem right?

    I have two questions, one is if you could find the defect or fix your laser.
    The other is how do I open the front of it?
