on the other hand you wont harm your eyesight so as you could with laser powers>20mw!!
not for the pens under 50mW. the 5mW units are almost always overspec!I own one, a DealExtreme one.
And most of the time the output is underspec. And they are way cheaper. Mine is really bright, and sturdy.
No. Nobody owns a 20mW green pointer.
Really?
