I'm an EE moderator and a member is having an issue with a Lasermax guide rod he got off the EE and he started a feedback thread about it
I personally don't know anything about the Lasermax guide rods having never used one myself, any help or guidance from someone in the know would be greatly appreciated.

They pulsate. They are not a dim single beam. The lasermax purchased was over 5 years old but is defective from the get go.
