The second major issue is I ordered a beam expander with the adapter needed to use it on their Striker series. Its been about 4 months now and I haven't received my new keyswitch or the other missing item. They told me they would send out another one, which in itself is frustrating because shipping took about 3 months. I contacted sanwu about the keyswitch and the other missing item (the second major issue) and after a week they contacted me and asked for pictures as proof. First major issue is I got the combo of all three lasers, and the 405nm was missing the all of internals to the keyswitch making it unusable without swapping it out of one of the other lasers. Its quite odd since they have good reviews, but maybe I got some duds. unfortunately that doesn't seem to be the case with these. I guess for the price I shouldn't of expected much but normally sanwu has pretty great quality to price ratio. We recommend our green and red laser pointers for beginners.įocus adjustable for engraving and burning The near-ultraviolet light makes fluorescent objects glow! The 405nm violet laser beam contains high energy and laser dot can be focused down to a very fine point which making this laser good for engraving objects. The red beam goes much further across the skys horizon, good for measuring long distances. With 200mw of power, our red laser pointer is powerful enough to ignite matches and dark color paper INSTANTLY when focused. Additionally, it is just enough to light matches and cut duct tape when the beam is focused properly! This green laser pointer is perfect for Astronomy! You will enjoy the extremely bright beam slicing through the night sky.
