Those prices are amazing ($27.99 for a 200 mw model), but they do warn you that customs may open them and take them if you're one of the small percentage of unlucky ones. Some of you have indicated you tested them; how did you do that? (for those of us electronically challenged)...? ________________________________ From: Siegfried Jachmann <siegfried@jachmann.org> To: Utah Astronomy <utah-astronomy@mailman.xmission.com> Sent: Thursday, February 21, 2013 2:03 PM Subject: Re: [Utah-astronomy] Green laser What do you think of this one? http://www.lazerpoint.com/p-100mw-532nm-green-laser-pointer-pen-black_611911... sig On Thu, Feb 21, 2013 at 8:23 AM, Chuck Hards <chuck.hards@gmail.com> wrote:
I picked up one of the ten-dollar laser pointers at last night's SLAS meeting. Hey, for ten bucks, how can you go wrong? It's been a few years since I owned a 5mW laser and I wanted to see if my memory of the beam visibility was good.
The dot is pretty bright but the beam wasn't visible outdoors from my suburban home location last night except dimly when directly on-axis. To be expected from a 5mW unit, my memory is still good on that score.
The included alkaline batteries lasted for about 3 minutes of intermittant use. I replaced them with a new set of alkaline cells and they only lasted about 3 minutes.
Obviously this unit is defective. There is some kind of internal drain even when the unit is off. I'll be contacting the gentleman who sold it to me, he included his business card in the box.
Anybody else who bought one of these units experience rapid, premature battery drain?
As of right now, I cannot recommend this unit, even at ten bucks. But we'll see what happens. I'm open to a straight exchange for another unit but if that one has the same problem, I'll ask for a refund and chalk it up to lessons learned about buying cheap. I'm not getting rid of my 20mW and 100mW units anytime soon. _______________________________________________ Utah-Astronomy mailing list http://mailman.xmission.com/cgi-bin/mailman/listinfo/utah-astronomy
