I have three 5mW green lasers pointers, 2 from ebay and 1 fron DX. None of them works as I would like. May be I can see the beam just the 2-3 secons after I push the button, then it becomes really weak or erratic. This behavior worsens a lot when temperatura is cold. All of them are the typical 5% aaa laser pointer.
I don´t not need a powerful laser, just a one bright enough to point the stars and that works at low temperature. Until 20$ would be fine. Can you help me?
thanks
