I came across this a month or 2 ago and initially resisted the urge to buy one. then I saw them go on sale. It arrived yesterday and I am very pleased with it. The LPM I have measured it at 66mW and it held steady. Mine came with a couple things not shown in the picture. Mine also has a fan mounted behind the diode and it plugged into the driver board. The TTL and power cables also came with it. I'll hopefully get around to taking some pictures this weekend. I just got off work s couple hours ago and have to drive somewhere out of town this evening.
