Subject: Re: Laser pointers source, please?
A second note on the harbor freight laser pointers; the pen-style models I
got are brighter and more tightly collimated than the keyring style
(probably the case in general for pointers). The keyring laser I have (I
only bought one of those) gets fuzzy at large distances, and cost more to
boot. Stick with the pens unless you need a small laser for space reasons.
P.S. They take AAA batteries, not AA as I said earlier.
