it serves the purpose very well
Nice product exelent works
It's just average as light penetration is limited to 2-3 metres
Not only is this great for the bikes but have found that the rubber strap will fit the gaps on the btwin cycle helmets. My daughter now has two of these on the back of her helmet which is great due to her being shorter and the light position on the bike is poor. great design.
At this price you're not going to get a super bright all illuminating light... but it works well as a heads up helmet light
A very good and bright light, but did slide on the handle bars. However, a little bit of 'padding' sorted that.
