Reviews

The actual output power of this laser is about 7000mW. The cooling system is very good, and it does not generate much heat even if it works continuously for one minute.

My job requires frequent diving. This green laser pointer works well for hundreds of meters underwater, and the laser beam is powerful enough to reach almost anywhere underwater!

We got this green laser pointer to ward off geese in our yard. They scatter every time it shines on them.

This is truly waterproof — no problem even 100 meters underwater! I recommend choosing the 2W version because it has a thick blue beam, and visibility is not enough if the power is too low.

It's a powerful green laser, and you can see the beam in a brightly lit room. The various patterns are very cool. Unfortunately, I got it as a cat toy and it's too powerful for that, as it reflects off the hardwood floor in my cat's face and was too large and bright a target for her to want to chase. It's too bright for indoor applications, but it would be great for the outdoors.

It is a professional high-power laser pointer. However, there is no safety lock.

From the parameters, this laser is very good, and the actual use exceeds my expectations. In the dark, you can clearly see the laser beam shining far away. It has multiple output modes, which are very playable.
It is highly recommended to laser enthusiasts!

This product is incredibly impressive. The green laser beam is incredibly bright, and it works flawlessly even from a considerable distance.

The 20000mW power is really amazing! I have bought other laser pointers before, but the output power is far inferior to this one.

This green laser pointer is powerful. The laser beam is visible to anyone who is looking in its direction.

This high-power laser is exactly as described. Its green beam will go for miles.

It's all right, but it will drain the battery quickly. It would be great if the two 16340 batteries were replaced with 18650 batteries.

The power of this laser pointer exceeds 5000mW. It would be better if the merchant could send a few more batteries, but overall, I am still satisfied with it.

As a red laser pointer, 1W output is rare. I can use it to light matches, pop balloons, burn darker-coloured wood, and cut through the black plastic electrical tape. The red beam is impressive in total darkness.

I got the 100W tube installed easily. It works perfectly, no issues.

My power meter showed it at 6800mW, which is more powerful than the website states. The blue beam is so strong that you need to wear goggles if you use it indoors.

These things are basically the same diodes that come in 638nm laser pointers, and I found them to be fairly easy to install.

This powerful laser can light a cigarette quickly. It really surprised me.

The overall review of the product is positive, as it's both powerful and inexpensive. Most importantly, its output power is genuine, and there is no false advertising.

This thing is powerful and long range. It can chase the geese away from the pond.
