i know hes out of business for bad business practice, my laser does ok, and i think all i need is a simple fix. i have the [SF*501B]*SF501B*445nm*Blue 2-2.4w model. problem im having is the focusing lens, its loose in the ring, and i can hardly ever get it to focus properly. How could i go about fixing this and where could i get one so i can use this thing right, thanks alot guys, you rock!
