Here is a Kryton Groove 445 build. It feels solid and nice. I build it myself. Kit from Dave(daguin). It has a groove drive. I set the power to around 720mw for a good runtime and long healthy lifespan. I heat shrinking the driver but open a hole for adjusting current. So just simply screw down the head and you can adjust the power from 540-1000mA. I believe the switch is fine I used it for a while and no sign of melting down. So sad it has to go, my first 445 laser, but need money. It will go for $150 with pp and shipping (US only).
