I think the warning from Steve, LSRFAQ, that these will all fail may have some people nervous about these lasers. I still have mine that is still doing just fine and shows no signs of giving up anytime soon.
I have two spare 575 modules I don't use, could replace one at a time. I use my pointers fairly sparingly anyway. Do you remember what causes the problem? I suppose I could just put another diode in it too.
I paid for one of each at the very beginning-- was given wrong PP addy had to resend the $$ and then the first fails started-- I was put off 6 or 7 times.. may have to settle for other items that Opt (China) sells. but no cash refund.. not a happy camper.
