Hi, I tried to search and didn't find anything on these. I purchased one after a friend was given one for his birthday. The packaging on my friends said it would project up to 300 yards. I was skeptical, but it was fairly impressive once we took it outside. I purchased mine from someone on Ebay and my sample projects fairly well - not sure exactly how far. Just curious if anyone else has any experience with them. The company does have a web site, but I was disappointed with the information there.
