    • It has 2 major flaws that restrict its use

      The USB connector isn't universal. It has a specific plug that doesn't fit in any other mobile device unlike other set of lights I bought in the past. Secondly, it has no strobe mode, and that's a major letdown because that's what you need during daytime cycling, specially when commuting in urban areas. At USD25 a piece there are better options available on other merchant websites.
    • Awesome product

      Used for More than 2 years
      Has been using for more than 2 years, was one of my first purchase with decathlon. Very bright light 5 start for that. power back up 2 hrs as mentioned, which is less and can be improved 4 stars for this.
      Response of the brand
      Dear Arpit,

      Thank you for sharing your valuable experience with us, this really helps us to improve our products. The focused light is definitely bright enough to ride on dark roads, the product also has one more advantage of running on power bank, you may try that as well during long rides. We would take the feedback on battery performance to improve it in the future. Thank you and keep riding.

      I saw my friends use this and I must say it's a good product worth every single rupee I spent. I only have problems with attaching it to my helmet (B'Twin 500) because the strap is too small to fasten across a vent and I'm not sure if it's waterproof in case it gets wet in a rain. Other than that I'm pretty satisfied, even though I used it for only one trip until now. 10/10 would recommend.

      Very good light, but could have put a better battery to go on for 4 hours.
