I bought a Violet laser from HighTechDealz and am amazed how powerful it is. I have a 60mw green of course its brighter because the wavelength, but it can only pop balloons and make some black things smoke, but my new Violet Laser is a different story. It pops balloons, light matches, melt plastics and something I didnt expect was was to be able to burn though a piece of white printer paper in 3 seconds and I continued moving the paper and burnt my initials trough the paper well it kinda looked like my initials it was hard holding the paper up and guiding the laser at the same time. What do you think the power would be in Mw's? I want to thank HighTechDeals for the high quality work and low prices. Stefan
