Amazing laser
So far so good! I've played with it on and off my laser cutter for a few days and it has held up so far. The power is great - it cuts through 1.8mm wood (popsicle sticks) in two passes with air assist. Very nice focus - down to a very small dot. The laser housing does not appear to get very hot with use, which is excellent.
Word of warning - the TTL input pin floats high, so this will turn on at full power if you just plug it into 12VDC. To fix this I added a 700 ohm pulldown resistor between TTL (+) and TTL (-) and now it works fine. I'm controlling it with the Raspberry PI 3.3V GPIO signals.

Good value, preforms as expected
Great powered riser - using it with my RX 470 4gb and it works well. Also has pretty lights that look cool in the dark.
