This started happening within 90 days for sure, but it's been a few years since I purchased it. If the laser diode has 'gone out', I'm curious as to how it can be so bright at first. Wouldn't a dead diode not come at all, as opposed to starting out strong and fading out after several minutes?
I see the cost of a replacement diode in the parts store is basically the same as an entirely new unit.
Thanks for the reply.
