I have been using it for a few years and it works like a charm. Sadly, the cable broke and it is impossible to fix or replace,so I'll have to buy a new system. I can't use Nova because of its meterials and dimentions lmitations.

I have had these lights on my commuting bike for 13 years and in that time they have covered 11900 miles. As they are flash only I use them as secondary lights to meet the minimum lighting laws in the UK, just in case my main rechargeable lights fail on the way home. My commute is a mix of tarmac roads and muddy cycle path. They have done the job for 13 years and I hope will do it for a few more.

First of all, I love the idea and mostly also the execution of this product. I have had both the front and back light for some years. Both lights add visibility, but the front light is not bright enough for the rider to see well in pitch black conditions, e.g. in the darkness of the Finnish winter, outside the reach of the street lamps.
If the cable gets ripped off the light by some a**h**e, like mine did, it is not repairable, which is a bummer. In cases like this, it would be nice to be able to buy again just the light with a new cable instead of an entire new set.

Almost impossible to install without taking the entire front wheel apart. I gave up after almost an hour trying to install it. Not worth it.
