Summary: Great Pointer
Comment: Product came quicker than stated, this is a great seller. When I put the batteries in and pressed the button to light it up, I thought it would be like other pointers, but it was much brighter. Great presentation tool.

Comment: Good product. Only grouse was that the laser warning sticker came slightly off when it arrived.

Summary: Has many uses .. but there are cautions to observe!
Comment: Please see my comment on the "50 mW" model [same seller] of this green laser in the rather excellent review by M. Byer but since I own the 30 mW model, I thought I would re-emphasize my remarks in a review of the model that I own but where the same 'cautions' duly apply. I also stated in that comment that while I ran the risk of my remarks being interpreted as a 'lecture', I felt the risk was worth it if 'only' because of the safety issues and cautions involved.
First and foremost, these are not toys! To reiterate -- these devices should be kept out of the hands of small children! While children may marvel at the effect the laser beam 'spot' has on household pets, particularly dogs and cats, as the pet tries to pounce on the spot or chase it, there is also the problem of the spot being unintentionally directed at the eyes of the pet or children just as unintentionally pointing the laser device at their own eyes or the eyes of other children and these lasers, especially the more powerful and brighter 'green' lasers, can cause serious eye damage with protracted laser beam focusing on the eye.
So too, be careful where you point such devices because other folks, and 'rightfully' so, I'll add at once, may not appreciate it and, worse, may let you know about it in no uncertain terms! Ditto pointing these devices at low flying aircraft or moving vehicles [et al] where 'legal' ramifications can enter the picture. The beam always tracks back to the source. Bright lasers to the eyes also temporarily destroy one's night vision in an instant and the higher the laser "mW" rating, the more risk is involved in terms of eye injury.
That all said, this 30 mW laser is 'very' bright although I noted that the laser label [on the front of the device] says: "Wavelength 532nm -- Max Output <30 mW" which of course means "less than" 30 mW although it's advertised as "30 mW" -- see the testing results the reviewer for the 50 mW model got on that allegedly higher powered model. These devices have all sorts of uses and I'm presently doing some outside experimentation with the device for mountaineering emergency 'location' purposes as the device has the capability of cutting through [rather than 'reflecting back'] dense fog, mist, falling snow and can produce a veritable light show if beamed on solid ice but thus affording rescuers a 'location' direction or 'beacon' if you will for the laser user who may be in trouble. Others use these devices for pointer presentation purposes [although I'll add here that a 5mW power laser should be sufficient for this purpose] or, indeed, giving their pets some fun in chasing the 'spot' and hence getting some indoor exercise for their pets. The key though is using the laser device 'prudently' while keeping in mind that it's not a toy and should never be given to small children to 'play' with nor focused on the eyes which can lead to serious consequences. BTW, and this comes as news to some folks, myself included by the way, both AAA [which this laser uses] and AA batteries are available in 'lithium' versions and these lithium AAA/AA batteries can have a much longer life-span than the standard AAA/AA 'Alkaline' types.
One last thing, if you do have small children [or grand-children] in the house, put the laser device out of easy reach! To a child, it's simply a neat looking green [or 'whatever' laser -- red or blue varieties] supposedly 'harmless' light show kind of thing but what YOU don't need is an ophthalmologist informing you that the child's eyes have been damaged! Secure the device! Fun and quite useful for multi-purposes it can be but a 'toy' it's decidedly not!

Summary: VERY Bright Laser! Great Value - Recommended!
Comment: The "30mw Green Laser" is a very powerful green laser that is the brightest non-professional (read expensive) laser I have ever used. The beam is visible for a LONG distance at night and plenty bright even in well lit rooms.
The laser comes with two AAA batteries so you can use it right away. Also, one reviewer noted that his did not come with the "Double Bonus LED Flashlight and Lens Cloth" but mine did (not that it would have influenced my buying of this laser).
For what you get and the price, this is a great deal! Highly recommended!
