I missed the delivery for mine yesterday which was at 6 days from the time it left hong kong, and so picked it up today and i love it. Its extremely stable and very bright. The beam diameter seams quite large though which is why it won't burn. (Not even a sharpied balloon). Its a very nice laser for star pointing. also, my trustfire protected batteries don't fit all the way in. I also like that the threads don't squeak.
If anyone can figure out how to somehow focus the beam even more, please sure. However i dont think its possible. If it was more focused im sure it would burn, its so bright how it is!
