Best ebay purchase ever

Looking back through posts here, it seems like people sometimes mention good buys or favorite purchases.

This is the coolest thing I ever bought from ebay. I can't recommend it too highly. It is perfect for star gazing. The beam is easily visible through the atmosphere. It comes with both disposable and rechargeable lithium cells of different sizes. The removable center barrel accommodates either size. Quality is outstanding. Intensity is amazing.

One word of caution: Don't aim it at people or highly reflective surfaces! I warned you.

    Seems like alot of battery power for a 5mW laser ???

    Also, what's up with the 60/5 second duty cycle ?

    I've had on of these 1 watt blue lasers http://www.wickedlasers.com/lasers/Spyder_III_Pro_Arctic_Series-96-37.html on order since June. Still waiting...

    There was a recent report on the BBC about laser eye injuries in adolescents in the US mostly from a variety of handheld lasers sold over the internet, mostly over 5mW output power, but not a lot over that. Some injuries were permanent. Some seemed to resolve over a considerable period of time.

    Bean,

    Good luck getting your merchandise. It's a Hong Kong company, and there are U.S. import restrictions on that class of laser. Here's the warning that DealExtreme (Hong Kong) posts on their high-power laser pages:
    United States Customers Only: due to new regulations enforced by the US FDA and PayPal, orders of >5mW lasers units shipped to the United States are no longer accepted. Orders that were previously accepted and unshipped will be cancelled and refunded to customers. This affects United States orders only.

    Important FDA Warning for all >5mW Lasers: FDA advices all customers that these lasers may be purchased only if you are NOT a citizen of the United States and you are NOT currently living in the United States.

    LOL! I wonder if they put the 5mW boiler plate there to avoid import restrictions. But there is no way this laser is 5 mW. 500 mW maybe.

    Just now I grabbed an ammeter. There is 1.3 W going into the laser head with a partly-discharged lithium cell. I don't know what the efficiency is. All I can say that the beam is very impressive after dark. It isn't just kids ooing and ahhing. It surprises me how many adults get all jiggy.

    For pointing out stars, planets, and constellations, it can't be beat. Can't count how many times I've pointed out fiery red Antares in the constellation Scorpius, or shown that if you follow the handle of the Big Dipper, you end up at Arcturus. Then my eldest daughter shows everyone up by pointing out nearly every constellation in the sky. (What motivates an attractive teen-age girl to memorize a star chart?!)

    Just be careful, when you're aiming it skyward, that there aren't any aircraft in the vicinity.

    Lasers are banned in Australia too. And it is illegal to point them into the sky because of the danger to aircraft.

    There is a rough inverse relationship between clear skies and aircraft. The best locations for star gazing seem to have the fewest aircraft. We have had no trouble at all avoiding aircraft.
    It seems crazy that in the vast interior of Australia you can't point a laser at the sky. Laws like that give legislatures a bad name.

    Vet, you may have cracked the mystery of how a laser above 5 mW can be legally imported. The "Military Style Laser Ray" has a pretty solid lock. It's not just a cosmetic gimmick.

    User , maybe I hope so that is what I was told by the wicked laser sales man and to be honest while I am not happy with my 400 dollar flashlight battery life , everytime I have delt with this company they have always been very honest and shipped me what I paid for . When I tried to order lasers from other ebay sources ther did not seem to know anything about the saftey lock making them legal and just told me they could not sell to the USA so we shall see. I would think Bean will get his before me since he ordered a while ago
    and I will no longer reck DVD players trying to get a laser that will lite a match I also have a few Axim kits that are no better than a 2 dollar laser pointer ... Bean can you let us know if you get yours?
