I was quite suprised with this item. It was purchased as a back up front light for road and occasional offroad use as I already have an upper market 'Cateye' light fitted to the handlebars.
Sadly though, this seems to out perform my Cateye quite considerably. At only a fraction of the cost, this little beauty gives a bright, wide area of white light, and has 3 settings ('dim', 'full' and flashing). Sadly all three settings are better than my LED cateye and I'm wondering if my £50.00 could have been better spend on a few more of these?!
Most importantly, the light is fitted to the handlebars using the supplied velcro strap, which ties around the bars and through the bracket on the bottom of the light. Very secure, and very quick and easy to fit/move/remove. As far as I am aware, the light is also compatible to fit most other standard fixed light brackets!
The light is supplied with a small USB stick, which attaches to the light by means of 2 small magnetic dots on both the USB stick and the light. Simply plug in and place light on USB stick to charge - takes about an hour, and lasts for approx 5-10hrs (depending on brightness setting).
Very highly recommended!
