I just got mine today SenKat. Thanks for the fast shipping. However, this thing is not as bright as the dvd burner reds I have been making, second it won't even pop a black baloon or light a sharpied match at any distance. My DIY red pops black baloons instantly and unsharpied matches very quickly. I tried 2 different sets of batteries and the focus seems to be fine so I did not try adjusting that.
