Hi, I am new here and I need help to buy a new laser.

1)- I need to know whats the difference between Portable laser, Handheld laser, and Laser pointer.

2)- Is this a trust site? laserbtb

3)- Can a 150 mW laser be visible at 2 km ?

4)- What u think about this laser (150mW)? HL 532nm 50mW-300mW

5)- Sorry for my English XD.

NOTE: I accept suggestions ^^

Thank You for help.

1) Nothing, just look at the dimensions of the laser and that will tell you the size. For laser glow and other companies they call pocket sized lasers handheld and the larger ones portable. This is not the same for every company though.
2) Yes, skylasers has been reliable in the past.
3) It depends on the divergence, beam size and wavelength of the laser
4) It looks like a good laser, I can't say though since I have never bought one myself.
5) It's fine :)
