Wildboy - Take a look at my threads on here as I have just purchased one of that type of Laser projectors (the 500mW RGB). They are not good - but - whom I purchased it from is now paying to basically make it up to something like what it should be. They are cheap yes but unsafe and not really legal for them to be selling them in this country. They are not CE marked!
If you want to ring me about it then please feel free. Number on my website below.
I will post more details later when I get home if you wish?
Jim
