That's exactly the same as the one from O-Like, right?According to a review here, the "new style" 200 mW red laser from Budget Gadgets is also a great choice.
Is there any post on this forum telling what lens you need and how you proceed to replace the original lens with the new glass lens?If you want, you can further increase its power and improve its divergence by buying a glass lens upgrade.
What plug do the O-Like chargers come with? And which voltage do they accept: 110V or 220V?( You might need an different plug)
