Very nice thing. Red beam. Projects one red line in angle of approx. 90 degrees. The line is focusable by rotating the lens. Heavily built metal case. Red and black wire for easy soldering. Beam quite strong. Could be very good for lightning up your DIY laser projects..from disco to EAN reader or holograph scanner.
I ordered more of these and must say, that all of them are not of the same quality. The case and wires are always the same and very good, but ability to focus the line varies. Some pieces are able to make thinner line than other.
Maybe offering a green or blue laser in this case?
