I bought the light mainly for daily transport around the city with the idea - mainly to be seen. Light fulfills this purpose for me. In my opinion, however, it is not entirely suitable for lighting for oneself - so that one can also see something. The luminance is sufficient, but the scattering angle is quite small, so it illuminates the maximum space directly in front of you, as if you were shining with a flashlight. It is enough for driving on unlit sidewalks and roads, but for evening driving I would choose something more powerful.

I tested it today and I'm satisfied. The price/performance/durability/weight ratio is unrivaled. The light shines more in a spot, but the afterglow is relatively far, which is absolutely sufficient for me. If you want to race through the dark at a speed of 40 km/h on unknown slopes, you need something stronger. The only thing that bothers me is that it cannot be attached to my helmet (I have narrow ventilation holes on my helmet, otherwise the attachment strip will not fit there). Anyway, I recommend it.

The brightness is great, it's relatively small so it doesn't interfere, I would prefer a wider spread of light, but it's quite enough for me in the city, the only switch between flashing and constant lighting is slightly uncomfortable because you have to hold the button, the assembly using the rubber collar is quick, I just hope that no problem, thumbs up for that price

SK Super svieti. Ako aj ostatni pisu, luc (kruh) mohol byt sirsi, ale plne mi to postacuje.
Trochu sa mi svetlo otaca na rajdoch, ked idem po nerovnostiach. Musim pod svetlo dat nieco nesmyklave a problem by mal byt vyrieseny.
Spokojny som aj s vydrzou baterie.

The brightness is excellent, but the optics are not of high quality. I would recommend the manufacturer to expand the cone of light a little for the given brightness. Optics for cyclists, even with other lamps, are not at the level that cyclists need.

Excellent luminosity, fully sufficient for my evening commutes from longer rides. You have to pay attention to glare from moving cars and cyclists (when setting the light to maximum power). I would have liked a slightly wider light cone.

The brightness is fully sufficient even in the dark in the forest (but not extreme in descents, etc.), compact, to my surprise, very solidly processed. It lights more like a spot, the cable is part of the package. Maximum satisfaction for this price

Light output and endurance satisfaction. The dispersion of light is slightly weaker, it shines in a narrow cone rather far into the distance. For me, the price/performance ratio is very good. I drive in the dark only occasionally and for that purpose a very useful light.

I tested the light and I can say that for the price it is a great product. The light has small dimensions, it holds well on the handlebars and the brightness is more than good. For me, a big plus for USB charging.

Fantastic buy for ridiculous money, I shine like a truck. In terms of price/performance ratio, it does not break records in terms of battery life, but for that money I will easily buy 2 for replacement. ?

Excellent light for the price. Light, nimble and although the light cone is relatively narrow, the luminosity is at a very good level and it is enough for moving in the dark.

Satisfaction. It lasts quite well and is enough for casual evening driving around the city, even through the forest. They are used by children on scooters or bicycles.

Great price/performance ratio, easy transfer from bike to bike, I will probably buy another one for the family

The light shines well, especially into the circle, but it shines enough into the sphere and illuminates the edges a little, but otherwise fine

Practical light, excellent luminosity. 3 flashing modes, 3 lighting modes. The main thing is to be seen!

It lights up great and, most importantly, it can be charged via USB, so I don't have to keep looking for flashlights.
