Hello,
Sorry for my english,
but my question is, i have bought a cheap green laserpen, but when i light it, it gives 3 seconds very bright light, and then a lot less bright light! the first couple of seconds are very nice , but after that it is crap.
thank you for your answer,
Tom

sorry.
how can i solve that? normally I put it some minutes at the heating,
and then it works fine,. is that good for the laser?

Greens are sensitive to heat they like to be a little warm and don't like cold. So if you hold it in your hand for a little and then it is stable it is normal. Sorry no other way to fix it that is just the nature of the cheap green.

Hi,

Did you try replacing the batteries? If you bought it from DX, don't use the batteries that come with it. Buy good AAA batteries or use rechargeables.

And if this doesn't help, than it seems that there is nothing to be done.
