Excellent value for money for an auxiliary light. 2 settings: Flash and constant although I always use it on Flashing mode with the main purpose of to be seen (as daytime riding light). Extremely easy and versatile to fit (got 2 on my mountain bike's fork and got 1on my road bike's handlebar)

Response of the brand
Hello Carlinn!

Thank you for the feedback on our VIOO 100 front light.  Firstly, I apologies for the experience you had on our product. Indeed the light is designed to last 32 hours on continuous mode, so there could be a defect on the product or the battery.  Please visit your nearest Decathlon Store to do an exchange of the light. On top of it, we will also give you a pair of brand new CR2032 batteries to prevent the same problem from happening again.

Great lights but faulty battery
Used for 2 to 8 weeks
I bought three of these but the battery ran out in one of them within a week. Will cost the same to get a new battery as to buy a new light
Reasonably priced light
Used for More than 2 years
Honestly, if you want to use it during dark, it won't work and it merely acts as an indicator for others. You will hardly be able to see in dark with this light.
Response of the brand
Hello Yogesh,

Thank you for taking time out to review our product. Bicycle lights fall under two categories - TO SEE and TO BE SEEN. The VIOO 100 Front light you purchased is a to be seen light only to serve as a indicator. If you are interested to see the road in the dark, please check VIOO 700 Front ight

Hope this helps. Thank you!
Great little light
Used for More than 2 years
Great light at really reasonable price. I bought this to replace one stolen when my bike was stolen!
