Luca front and rear

Very comfortable you can put it wherever you want on the bike and for me it has good brightness

Practical but rather expensive

I find this little lamp very expensive. Plus I've lost 3 (they fell off the helmet). It's expensive

Very good visibility. eco-design to improve

I bought several copies a few years ago, still operational. New bike for my daughter to equip: we're buying again! Very practical to be able to change the type of lighting: flashing / steady, red / white. So it’s versatile. Very good visibility when flashing. The design can be greatly improved from an “eco” point of view. It's so much to speed up on this :) - don't deliver the little cable for charging!! It's 2023, we all have boxes full of USB cables. I have just bought 3 lights = 3 cables which will go directly into a WEEE bin. It's absurd ! - If no cable: the size of the box can be reduced. New economy. - you would have to switch to USB-C. It's micro-USB, which is now an obsolete format. - I find the flashing mode too fast. By slowing it down a little, the battery would last longer. This is more practical for the customer who would charge less often. It’s both more eco-friendly and more practical for the customer. - the cardboard packaging does not seem to be treated, which is very good. If so, indicate so. Show off what you do well so the customer understands. - well, but that's more complicated given the small format: the battery would have to be replaceable. I don't know if there are batteries small enough for this format. If it were sold without a battery (and without a cable), the price could be significantly lower.

I had the old model, which I was satisfied with for its autonomy. The lighting is more powerful. It's better. Running use, flashing lights.

Great product

Very solid, good autonomy, plenty of fixing solutions. Sufficiently powerful in the city. Reversible front/rear, it's practical. Only flaw: not always super easy to hook/unhook on compatible soft bags.

Top product,…

Top product, very good autonomy, fast charging, good visibility, very reassuring, I use it especially during the day for mountain biking on the road. but so compact and powerful that I also used it on vacation as a flashlight clipped to clothes (efficient hanging system), it can also be used for tinkering or troubleshooting, also ideal for signaling a pedestrian. An excellent product. I'm going to buy more to leave in cars. I highly recommend this lighting

Great if it doesn't fall of

I was very satisfied with it until in fell of my bike while riding in a ravine in the Ardenes and couldn't recover it. The fastening could be much improved so it doesn't fall off. Quite powerful for such a small and light device.

Truly EXCELLENT to be…

Really EXCELLENT to be seen, day and night, on the outskirts and city center, for the daily journeys home/college and home/high school for my 2 boys. Be careful to take care of them and not forget them, because it’s still €20 for one. I have already bought 7 in 5 years: 2 stolen (forgotten on the bike) and one badly hung then crushed by a car :-(
