Great for amateur astronomyJul 09, 2010
I have only had this for one day, but I can say that it is easily powerful enough to point out specific objects in the night sky, even before it is completely dark. I live on the edge of a major metropolitan area with significant light pollution and could still easily see the beam.
This laser is also easily bright enough to direct someones attention in a very well lit room, regardless of size. If a red laser pointer isn't up to the job, this one will be. I would keep a red one around, though, as this one was too bright to me in my house.
Most of my pets didn't seem to care for it and ignored it, even though they like to play with red lasers, so I would stick with cheap red ones for that purpose. The one that did pay attention to it still didn't play with it, just watched it.
As for construction, the button slides around a bit, but everything else seems to have a tight fit. So far the loose button has not had a negative impact on operation. It looks nice with a matte finish on the black portion. It simply says "* Laser Pointer *" on the pocket clip, no other markings except for the laser warning label.
The laser requires that you hold the button down to keep it on, but I prefer it this way as a safety precaution. The laser is extremely bright and I wouldn't want it on if it were dropped or carelessly handled.
The product comes with no details about the manufacturer, distributor, or warranty, so don't expect warranty service. The only box marking is on the inside of the top: "Laser Pointer".

This is why people are having troubleFeb 12, 2012
Watch Video Here: http://www.amazon.com/review/R1YJ7SL1P1LKOW This pointer is wonderful. The beam is solid and strong. The only problem is the power will be down if the pointer is cold. That is why people are having a hard time with it in the other reviews. It is an easy fix, just warm it up in your hand or store it in you pocket if you plan on going outside when it is cold. Highly recommended, steal for the price.

Rolling the DiceNov 07, 2011
By J. Jordan
Well, now I understand the mix of reviews. The quality control for this item is terrible. I ordered three. One worked great. One started out bright when I first pressed the button, then quickly faded. The last one was dim no matter what I did.
So to those who get a good one, the product is excellent. But to those who get the bad ones ... no so much.
Buyer beware -- you are rolling the dice with this item. I love the one that works, but one out of three isn't good odds.

Works, but has intermittent problemsOct 11, 2011
By Richard Marubayashi
I bought 2 of these lasers, because after reading of other people having problems with them, I decided I should get 2 in case one turned out to be defective. And at such a low price, there was little reason not to.
They arrived in good time, even a little earlier than I expected, so that was nice.
I immediately popped the (included) batteries in, and pushed the button. Nothing. I thought the El Cheapo batteries might be dead, but first I checked the instructions to see that I had them in the right way (the unit itself has no markings to tell which way to insert the batteries). The instructions say to "insert batteries with the positive end upward", and that's what I did. So I tried fresh batteries, and still got nothing. So I tried turning the batteries around. Bingo! The instructions are wrong.
I took both lasers on a camping trip to use in pointing out stars, and when I unpacked them, they didn't work! Nuts, I thought the package might have pressed the button, running the batteries down. But I tried taking the batteries out, blowing in the tube, and putting them back in, and this time I got a beam, but it was rather weak. I still thought the batteries might have been partially drained. so this time, when putting them away, I took the batteries out and packed them in the little battery storage slots in the package. This should probably be standard procedure anyway, in case of battery leakage.
When I got home, I pulled them out again, and they still had problems. So I peered down the tube, and realized that there was no special contact at the bottom -- the battery just presses up against the inside of the tube, and that completes the circuit. Not a very robust design, if you ask me. So I took a pencil, and used the eraser to clean the inside of that end of the tube, and reinserted the batteries. Success! The beam is now as bright as ever!
So the circuitry is fine, but you just have to make sure you get good electrical continuity at both ends of the batteries. A pencil eraser worked for me, but it would be even better with a tiny patch of fine emery cloth.
For a 5mW laser, I'm impressed at the brightness of the beam. My son and I had fun just shining them at the ceiling in a dark room. Amazingly bright. With some small mirrors, you could have fun setting up an obstacle course, or pretend "burglar detector". And outside, they are great for pointing out stars.
Overall, I'm happy with this laser pointer. It's annoying that I had to tinker with it to get it to work right, but at four bucks each, I can't complain.

nice price for a decent green laserMar 11, 2010
Out of curiosity I bought 1 of these last summer, then after testing for a whilepurchased ten more as christmas gifts for family/friends.
I tested them all out before giving away. 6 or 7 had very strong, even beams even with the no-name (included) batteries. My father/brother and best friends got these. If you haven't seen a green laser you'll be amazed at the intensity and distance you can get out of it. Too bright for indoor presentations though!
2 or 3 of te ten had weaker beams, but still stronger than a quality red laser pointer so I still gave these out.
1 had a bright hot beam to start, but ever time after 1 or 2 seconds would 'weaken' significantly and slightly flicker. I didn't bother sending this back, just keep it as a back-up.
The original one from summer 2009 is still going strong, probably use it every week or so just to have fun. Outdoors in heavy fog/mist the visible beam is especially impressive.
As others have said be very aware that not only a direct shot to the eyes is very dangerous, but also a reflection. It doesn't take a mirror either, any smooth surface (i.e. a window) can will reflect enough of the beam to do permanent eye damage, and something like a glass or complex shape will send reflections in unpredicatble directions.
Anyway, since I've bought so many though I'd leave a review of this quite nice pruduct for the price.
