Not water proof

Claims to be rain proof and have 3 hours battery life, mine has neither. After 2 weeks use, I have not got more than 90 minutes use before needing a charge and it now has water inside and won't turn off.

Thank you for your feedback regarding these lights. Indeed it seems that they have failed on both counts.
I have sent your comments on to the team who manages this item at b'Twin.
In the meantime, please don't hesitate to return them for a refund.

Bought this for commuting, well worth the money

Not even 1 recharge before it stopped working

After buying I used till it ran out of charge and that’s it, it does not recharge. If plugged in it flashes but they’ve obviously used rubbish batteries. I haven’t kept the receipt so it was essentially an expensive disposable single use object. Very disappointed. AVOID

I'm sorry to read that there was a fault with your light unit. please return it to us for a refund or an exchange.

Stops working after only a few recharges

I've bought 3 of these over the last year and a half, and was impressed at first. Very lightweght, decent battery life and good visibility for commuting. The first one lasted for a year before failing to recharge, and was replaced. The next lasted for only 3 months, which was rather disappointing, but I replaced with the same type as I had been happy with the first one. However , the third one was bought just before Christmas, has only been recharged twice, and will no longer charge at all.

Thank you for your comments regarding these lights. I will forward them on to the product design team at Decathlon Cycling. I can well appreciate how frustrated you must feel.

The light is smaller than I expected however, I’m glad it is as it fits perfect to the back of my rucksack. Even though it’s small it omits a very bright light and an added advantage is that it can be recharged via USB so I carry a portable USB charger just in case it’s needed. Brilliant little light that I’m glad I purchased.

A lot of flash in a little box!

These are great! Very bright and easy to attach to pretty much anything, I just wish they came with some form of instructions.. like.. when I switch them off a secondary led flashes away.. what does this mean? is the battery dying or happy? or is it just saying goodbye..

Clip light for helmet

Rechargeable clip light for helmet. Very good when cycling in the dark.

Good clip on light

I haven't tested how long the battery lasts in practice but this seems to be a good clip on light to put on the tail of my cycling jacket. Nice and small and light weight.

Excellent value for money

Simply cracking little light with great visibility.

Small but powerful

This is a tiny light but it's very bright. it fixes on with a rubber type strap, which is ideal because my rack has very little in the way of fixing points. The only thing I am not so keen on is that it seems difficult to switch off sometimes
