    • Not waterproof or reliable!!!

      Used for 2 to 8 weeks
      Bought this as a replacement for VIOO 300 light but it has the same inherent faults - after being used for a rainy ride it has now gone haywire, after charging up it won't switch on properly, then won't switch off and now it's switched on on it's own and won't go off. Yet another light I'm returning to Decathlon, these are useless.
      Ok when it worked
      Faulty after using in the rain

      Thank you for your review of this product, I will forward you're feedback onto the product manager. If you could let me know how bad the rain was which affected the light that would be great.

    • Good but watch for your frame shape

      Useful and effective, it's rather better as a rear-facing fixed or flashing light rather than showing the way forward. Its rigid structure means that it doesn't sit too comfortably around a square post, but that is not a major issue.
      Good rear visibility

      Really happy with this. Great value.
      Price, visibility, battery life
      Nothing apart from clarification on the above
      Response of the brand
      Thank you for your question regarding the "legal" point.

      To be brief the 320 model flashes but under some laws (and in the UK as well under the RVLR regulations) a steady beam of light must be emitted to conform (there are a few other conditions as well). The 500 model only offers a steady beam therefore conforms fully. In Germany for example, they are extremely strict on this point and flashing lights can not be sold as bike lights. Seeing as we sell throughout the world, the information we provide always errs on the side of caution.
      It has to be said that the fine details of RVLR are seldom enforced, and provided you show some kind of white light in front and red behind, it is very unlikely you'll be challenged.

      I hope this helps clarify the situation for you.
