DON'T USE WITH A 9 VOLT BATTERY!!
I've ruined two of these thus far using a 9v battery to test it. Didn't take long to do either. Was very bright while it lasted though...Editors Note: These units clearly state 3 Volts

Laser Power
The laser works as described, as powerfull as an average laser pointer pen while running at 3.3v.

Polarity
Does this device use standard red/black polarity? Editors Note:
Yes Red positive, Black negative

A customer from CA, USA
Module is case Positive, +
The red is +, and black is -, and the case is essential connected to red, as the case is positive. Great for mounting in a metal housing, and using the housings as the positive power lead!

Does the LASER MODULE need a current limiting resister
This was asked but not directly answered.

I just tried it without any resistors @ 3v and it works fine, no resistors are needed!!
