Zeus Pocket - Powerful Cyan Laser Pointer 130mW / 488nm

diode pops out toward lens. you must put an indentation around diode . there is one already on the other side. that way the diode doesn t pop in toward battery. Love color and it is really bright . too bright to be looking at spot for too long.

The laser has a beautiful blue color. It stands out from the common green DPSS lasers, while still having a beam that is highly visible at night. (Don't point it at people, animals, or aircraft!)

This laser didn't work when I first got it. It is clear that its flashlight-like housing was designed for a battery with the (-) terminal on the spring contact adjacent to the laser diode, and the (+) terminal on the flat switch contact in the cap. Other variants of the Pocket laser work this way, but the cyan laser diode has opposite polarity. So the instruction sheet that came with it basically tells you to put the battery in backward from what the physical design of the body expects. And it doesn't work reliably--the (-) terminal of battery ends up not touching the switch contact at all (preventing the laser from turning on), or touching both the contact *and* the cap body (preventing the laser from turning *off*). I emailed Zeus about this issue and they suggested bending the switch contact in the cap outward. That works! But it feels like a hack, and I wonder if the spring and battery will slowly flatten the bent contact and bypass the switch. Really, Zeus should have moved the spring contact to the cap.

The charger seems pretty flimsy, and the bizarrely-worded sticker on it doesn't inspire confidence - but it did charge my battery to exactly 4.2V as advertised.

Good laser

Late at night in the dark it feels like the power of a Sith lightning moving in a line!

Much more visible than the usual blue since it’s closer to green. Somewhat less dangerous than blue too! But it can still burn things up close. Cyan is the best color for a general laser
