Right now I’m a bit behind on my review, but this laser has had my attention for a while. I was able to test this laser a week or so ago on a Coherent Power Meter here at university. Here is my review of the “250mw Mini Flashlight Style Adjust Focus Blue-Violet Laser Pointer” from PriceAngels.com.
Shipping, Just as a reference I am based in the eastern united states. I placed the order for this laser on Saturday, 10/7/10. The package was delivered on 10/25/10. It was delivered in the typical bubble mailer.
I open the laser inside of the packaging there is a generic cr123 battery and the laser. I go and put the battery and and come to the realization that the laser has no polarity markings on the laser, in the packaging, or even on their website. I was eager to try this laser out because it actually came with a 250mw 532mw warning sticker on it, and “Green Laser Pointer” was printed on the box. So I turn it on and I see nothing. I then start to turn the focusing ring and a faint purple dot with a yellow outer ring appears. Kinda disappointed I change the battery it came with to a charged AW cell I had. No notice able difference was observed. Any distance above a foot or so the focused dot can’t be seen in a lighted room, making this laser not even capable of being used as a pointer.
About a week ago I was able to use the LPM they have at my school and the laser varies between 2-5mw. It starts out at five and within a few seconds it settles down to 2mw. Hmm That is less than 1% of the advertised power. :-/ I after I got the laser I opened a ticket on site. After sending about half a dozen pictures of the laser to them over the course of a week, I was offered a 14% refund or a $5 refund on a $35 laser.
I am not happy with how this worked out, and I have no plan of giving PriceAngels.com any business in the immediate future and I wouldn’t recommend them.
Images are compared to a “5mw” ebay 405nm pen laser.
