Which laser pointer is better and worth it?

Which laser pointer out of these would travel the farthest?

• I barely know a thing about lasers but I have someone who wants one and I thought it would be nice to get them one for christmas. They told me they once saw one that shot for miles and from how fascinated they were with that I really was hoping to get them the laser that can shoot the farthest but is still legal in the united states. Here's the ones I was able to find that I thought were worth deciding between, with a little background on why I thought they might be the one I'm looking for: I ordered this one yesterday which claims that it travels 5 miles http://www.ebay.com/itm/Laser-Lazer-PEN-Pointer-HIGH-POWER-2011-Green-5-miles-/390342116229?pt=LH_DefaultDomain_0&hash=item5ae2340385 but after I did I read online that 5mw lasers are the strongest, and this is only 1mw. I found a laser that claims to travel 5 miles and that is 5mw and I don't know if the power step up from 1mw to 5mw is something that could make it travel farther, but here's the listing http://www.ebay.com/itm/5mW-532NM-SUPER-MONSTER-GREEN-LASER-5-MILES-RANGE-MILITARY-GRADE-U-S-A-SELLER-/230701838454?pt=LH_DefaultDomain_0&hash=item35b6e6b076 And then I found two cheaper ones that are 5mw and if that is the only thing that determines the distance I would be interested in ordering one of them. One is red and one is green, I don't know how much that changes either, if anyone does i would appreciate any help, but here's the cheaper green 5mw one I found http://www.ebay.com/itm/5mW-532nm-Green-Beam-Laser-Pointer-Pen-Newest-/280765875972?pt=LH_DefaultDomain_0&hash=item415ef34704 And here's the cheaper red one I found http://www.ebay.com/itm/2-1-5mW-650nm-Red-Laser-Pointer-Flashlight-Keychain-LED-Faraway-Silver-/230695469005?pt=LH_DefaultDomain_0&hash=item35b6857fcd I was hoping that if it were narrowed down to more than one that would travel the farthest to order the cheaper one, and I also wanted the most visible one as well. I don't know if green is more normally visible than red but I know that also depends on the mw and nm, after reading about lasers on wikipedia. From that I tried to figure this out on my own but I only figured out that 532nm is the most common for green lasers and that 670/650 red laser pointers are less expensive. Here's a quote incase anyone wanted to refer to that "The least expensive laser pointers use a deep red laser diode near the 670/650 nanometers (nm) wavelength. Slightly more expensive ones use a red-orange 635 nm diode, more easily visible because of the greater sensitivity of the human eye at 635 nm. Other colors are possible too, with the 532 nm green laser being the most common alternative. Yellow-orange laser pointers, at 593.5 nm, later became available. In September 2005 handheld blue laser pointers at 473 nm became available."

• Answer:

  It seems to be about price so y not just get the cheapest your doing your research you dont need no help the decisive process carry on as you are and use your intuition
