Good lighrs

Very bright and a good price
Lights won't hold charge, shockingly bad component
Used for More than 2 years
Bought the lights, worked fine for the first 6 months. I then had to go away for a year an a half because of work. On return, nearly 2 years after purchase and on;y 6 months of actual use, the lights won't hold charge. They will only power when connected to mains, not quite the purpose they were purchased for.

I am extremely disappointed after paying around £20 for them. It is shocking how poor quality components they have inside if they die simply for not using them. I see that you provide a 2 year life warranty, which means these lights are out of it. I really can't recommend this or any product from this brand as I imagine the same happens with all their products.

Are you trying to force recurring revenue by forcing people to buy bike lights every 2 years? Shameful.
Response of the brand
Dear sir,
I have just replied directly to you.
I would like to confirm that we will replace the item under warranty and that we do not seek out at any point to make our items become faulty after 2 years.

B'TWIN VIOO 300 USB BIKE LED LIGHT SET - BLACK
Used for 1 week or less
good whilst working but not anywhere near as good as normal battery lights. Only lasted one day and required charging. A wrong purchase and will have to buy a more reliable set. also a bit pricey considering the lack of longevity of energy.
Response of the brand
If fully charged, this light set should last up to 5 hours on continuous beam. If this is not the case, then there may be  a fault with one of your lights therefore please return this to us for a refund or an exchange.

Good to be seen by not great at lighting the way.
Good for city riding
Used for 3 to 6 months
I love that these are rechargeable and lightweight. I plug them into my computer while I'm at work and they charge quickly. The have a little LED indicator for charge status (red for changing that turns green when complete). They're small enough they fit easily into my handbag and are easy to remove from my bike when I park it. The white one is not bright enough for unlit roads but it works well for city riding (where there are almost always streetlights).
Excellent 'be seen' city lights
Used for More than 2 years
I've been using these lights for years in London and really like them.
Just wish you could still buy them separately ie not in a set as I'm always losing the back light. So would be good to just replace that and not have to buy both each time.
Other reviewers have said they don't give a warning when the battery's about to run out, but that's not true - you always get a warning - you get a red light on the front light and a green light on the back light when the battery's low.
