Don't buy them - quality issues
on 15 December 2015
I would like to review these lights positively, because they are bright (but not too bright for city riding) and easy to attach. However, as other reviewers have mentioned, some of them don't connect properly to the supplied USB cable, making it very hard/impossible to charge them. Out of my pair, the back light is fine and charges without a problem. However, it's proving impossible to charge the front light because it just won't connect to the USB cable.
I complained to the seller (Dennis Winter leven ltd), who said I should return the light for a replacement. I did this (at my own expense, of course). I did not hear anything from the seller for several weeks. I had to send them two reminder emails before they finally sent my old light back with a short note saying "works fine :)". I emailed again to complain and received no reply. Really awful post sales service!
There is another thing wrong with these lights - although I like the way they attach to the bike, the clip on the back (which the bungee attaches to) seems to be made of quite brittle plastic which breaks relatively easily... this may be just my bad luck though - the clip on one of mine broke when it was attached to my bike and my bike fell down. When the clip breaks, you have no way to attach the light to your bike.
So - these are lights that don't charge properly and don't have a long-lived build.
