I got this 2 watt blue laser from China It looks very much like the Artic Laser but without the bells and whistles,I saw some demo of blowing up balloons,at 18 feet.This Laser I have melts and makes a hole on black plastic at 30 feet measured distance,also blows up a baloon al 30 feet,before testing I put my hand on the beam to se if it was warm enough,it burned my hand,then put the plastic and made a hole.Im thinking this 2 watt laser has much more than 2 watts.Taking the Artic Laser as example is there a way I can get to the battery spring?It cost me 199.00 dollars,12 days to arrive.They have many at good prices and 3 month warranti,link is Freemascot.com.
