Very powerful, it can light up the night even 2-3 kilometers away.
Be careful with children, it has such a high intensity that even if it points at a nearby spot, the reflection is so strong that it becomes irritating to the eyes. Needless to say, pointing it directly at the eyes is out of the question.
The attachment (head) at the front that splits the beam into hundreds of smaller ones is also very nice.
The only thing I had to deal with was that it was a little difficult to manage to unscrew and remove the "head" for the first time. After that, I got used to it.

Terrifyingly powerful laser pointer! You turn it on inside a room and the whole place lights up! Very long range.

edit: it does not charge.
they sent me with micro USB instead of typeC USB. order from "device gadget". nevertheless, very good laser device at a very low price

Guys, for its price it's unbeatable. Rechargeable and very powerful for amateur use, get it without hesitation

the distance is superb [at night of couse].
the only drawback is it needs recharging regularly [lasts approx. 1-1.5 hrs].

Amazing for only 10 euros! battery lasts for 20 to 30 mins (depending on use). It has a powerful beam that goes at least 10 km far! best buy ever

I actually added it to my basket in order to get the free shipping discount. But hooooly moly it's powerful. Even during a sunny midday you can point out things easily from afar!!!

Very powerful, suitable for sky mapping in the night sky for pointing out stars and planets, but extreme caution is required when using it in the night sky to avoid aircraft, airplanes, etc. because it probably exceeds 10-15 kilometers and of course it goes without saying that it should not be used by children—this is not a children's toy

For the money, it's very good; in the dark, the beam can reach enormous dimensions. Imagine, I was in Marousi and aimed at the mountain of Penteli, and it reached it. For €5, the best thing

It is very powerful to play with a cat .. the charger does not connect to your socket outlets, I used an adapter for UK sockets.

I ordered the product that was supposed to come with a charging cable.
In the end, it came with a back cover that you unscrew, and it has a built-in USB, and you plug the whole laser as it is on the PC to charge. I had to go and get a small cable because, of course, you can't put it to charge on the laptop in any way.
Apart from that, the laser is satisfactorily powerful.

I should have given ZERO stars! The product came with a charger incompatible with any Schuko socket! When I called the company (entry.com.gr), they told me to send it back at my own expense!!! Tragic..

It is indeed very powerful, but since we got it for the cat, we have put it aside because it seems quite dangerous for inside the house - it hurts your eyes in 1 minute.

It is powerful, okay..
But the fact that the charger does not fit in sockets (and even if it did, it is still useless, completely fake) prevents me from giving it a higher rating.

Unfortunately, it has a major disadvantage. The charger does not fit into a socket properly because it has small prongs.

It does not charge with USB as its name suggests, but it has a separate charger which, however, does not fit in all outlets, as it has very small prongs! Nevertheless, in terms of intensity, it is very good! Practically, it reaches as far as the eye can see and you can distinguish

I do not have a measure to measure the power, but it can reach more than 0.1W. Very good if you are interested in lasers and want to experiment with them, but be careful. Even the perfect one on the wall can burn your eyes if you look at it for a long time, and obviously if you aim the beam directly at your eye, it takes less than 0.5s to cause permanent damage. Finally, cheap green lasers often do not filter the infrared (invisible) radiation produced, so even greater caution is needed with this one.

It is NOT a USB rechargeable LASER but with a key, a rechargeable battery, and a battery charger.

Good but its battery discharges after 5 to 10 minutes of use. By the way, its range does reach 18 km indeed.

Very good laser. The charger goes directly into a simple socket and not into a socket with small teeth because it has very small teeth. It doesn't even fit in a multi-socket.
