Great light.
Band developed a cut
Used for 1 week or less
Recently purchased for my bike . Hardly used it for a week. Found the band attached to the rubber casing developed a small cut & is growing. Fitted on the seat post as per the description video.First time disappointed with a decathlon product.
Rubber strap broken
Used for 2 to 8 weeks
The rubber strap broken after i had a minor fall. The strap also looses its position after long rides hence making it susceptible to loss.
Response of the brand

Hello Aftab,

Thank you for taking the time to give us your review. We have not had complaints regarding the rubber straps on the vioo 100 lights. We have given it rubber straps for easy removal and installation. If the strap is stretched beyond a certain point due to an impact it could brake. I remain available for more questions.

Hello Sheethal, 

Thank you for taking the time to give us your review. It is possible the battery has drained out. If it is not the battery, please return the light the next time you visit decathlon and ask for a replacement because the product is covered under 2 years warranty.

Avoid this product
Used for 3 to 6 months
I have purchased this same product twice and both times I've lost the light since it simply fell off my bike. I highly recommend getting a product at a higher price point, instead of saving cash on this one. My suggestion would be to buy a rechargeable rear light, which will last longer.

Hello Abhiram, 
Thank you for taking the time to give us your review.  It is very rare that the product falls off because the rubber strap has a flap that stops it from rolling out to fall off. It also depends on the place where it was strapped on to. It is best designed for the handle bar and seat post.

Used for 1 week or less
it nice bright back light
but i felt it should have had a usb charging
Rear white plastic
Used for 1 week or less
Got this at the store in poonamalee, Chennai. However, when i had opened it after getting back home, i found that the rear white plastic part housing the batteries was a little off in alignment. Try as i might it wudn be as shown in one ve the images above. While this isnt a deal-breaker, i am honestly a little disappointed to see that.. My only suggestion to buyers, please open the packmwhile at the store to check it
Decent two modes for 6tye price
Rear white plastic s off position
Excellent value for Money

I actually bought two red ones and put one on each side. Alone they'll probably not be amazing but together they provide a decent glow at the back. Not had any issues with getting them soaked, or with the straps breaking, so no complaints as of yet
Tiny, cheap, easy install, good backup/secondary
Not overly bright alone, but who cares?
