Works well for all situations.

Great product and great service

I bought this to use in a bicycle, it's very good, very happy customer.

Instructions are fine but do not clearly reflect light setting. Nevertheless this light is still very good, especially for the price. Very bright and very light.

This light will work as your normal usually bike light but love the feature that makes it go brighter as you slow down functioning as a brake light on a car would, I think this is great and that every bike light should he the same as this. I haven’t yet worked out how to get the auto on/off to work but in manual mode I couldn’t fault it it’s small light and the easiest to fit and to charge really impressive.

Very good additional bicycle light.

It only worked for s as few minutes I had to charge for hours

Very good so far
