Easy to attach, remove and battery long lasting
I took this for a couple of rides, front light battery gave out after about 1.5 hours of use with a very weird "turning off even if there's still battery left function", had to spend the last 5 minutes with my finger constantly pressing the button to get the last bit of light until I got home. I connected both lights to charge them and went to sleep, but when I got ready to use my bike again the following day, I found out the front light didn't turn on anymore. I tried connecting it to 3 different usbs using 2 different cables with no response at all. Going to ask for a refund tomorrow since this is absolutely unacceptable.
I hope you were able to exchange or refund the lights and that the new set works well.

Great quality! Easy to fix to bike and quick to re charge with double usb connector provided
I am normally a big Decathlon fan.. I bought these without looking at the battery life.. 2h & 4h. I'm commuting 45min morning and evening.. I have to recharge every day.. I would not recommend buying this product. For such a bulky light battery life should be better.
So easy to fit to bike, no tools required, easy to recharge
Lights are bright enough. Very easy to get on and off. Inconspicuous so they are not a target for theives. However the front light seems to require a daily charge. Plus the wires supplied are to short. We don't all use a laptop to charge them.
These are a really good value set of front & rear lights. They are charged quickly (within an hour) via the supplied USB cable (nb: you will of course need a normal USB to main socket plug like the kind supplied with a mobile phone). They attach to the bike via a strong stretch rubber connector - so no fiddling around with screw connectors. The brightness of both lights are really good ...can't say how long the charge lasts as I've only used them for an hour at a time but this seems pretty good so far. Highly recommended..
Loved the way can be charged even on I phone lead
At the price the luminosity is not outstanding. But adequate. There is no flashing function which is surprising.
A little disappointed in how long the charge lasts, but the beam lights up the road well. Would have expected some flash modes for the price.
Could be better. Rear light appears to be upside down, as the diagonal section appears to be wrong way round. Front light only 1.5hrs charge max - not good
As above, decent beam when charged, easily fitted in seconds, small and easy to store, DO NOT FLASH, flashing doesn't only save power it is also some what more noticible in the dark on paths and roads, the front beam for example looks like a torch from a pedestrian point of view, flashing would be more obvious that a bike may be coming other than a dog walker.
