Powerful laser, they sent me the one with 4 heads with various designs. Only negative is that you have to press the button many times for it to work.

If I hadn't insisted on pressing the button several times and with pressure, it would never have turned on and I would have returned it as defective. Also, it is not suitable for presentations in any case, as it is very intense and bothers the eyes. On the positive side... it is a very powerful laser.

Very powerful, far from children's eyes, I look at the beam on the wall at 3 meters and my eyes tear up, be very careful, vision is not a game
and those who say that it shakes blame the batteries many times because it literally devours them so strongly that it is

Sometimes it fluctuates in brightness, meaning it flickers. It probably doesn't make good contact with a battery. Overall, it is a very powerful laser and easy to transport.

Very powerful laser.
Even if they said it's 50mW, I would believe it.
It's not suitable for pets.
If it passes over their eyes, they will be harmed.

If you have a lazy cat that sleeps all day and gets bored, just get a laser pen!!
Ours has been going crazy since yesterday!!!
It goes at 100km per hour inside the house and even pulls handbrake turns!!!

Extremely powerful and convenient for certain tasks. It is easily visible during the day.
Too powerful for short distances (e.g. presentations, teachers, etc.).
Very annoying and potentially dangerous for playing! Not suitable for such use.

Nice and quality seems, only minus that sometimes the intensity decreases suddenly, I hope it's not a bad sign.
EDIT: After a few months it works perfectly, I changed batteries with higher quality ones and it kills
