I just recieved my host and driver today and assembled my 2 watt 445nm laser, all was working well, then after charging my batteries i put them in the host and started screwing on the end cap and the laser turned on, clicked the button and it stayed on, something in the switch had failed and now it is on as soon as i screw the cap in, this is just another example of why you should have your laser glasses on before even installing the batteries, had i not been wearing them and the laser happened to be pointing at me or a reflective object in the room i might have been on my way to the eye doctor... be safe everyone, these things are not toys, but everyone already knows that, but just saying it to add to the warnings
