You WILL be seen
The light is well built and the two long/wide adjustable rubber straps are great.It's easy to remove and replace yet sturdy enough for barely move while attached.I've used the light in all sorts off weather and terrain and it's never let me down.Simple to charge and lasts age's on the "low" output setting, I never use it on full power because it’s too bright!Suitable for any type of bike and any age group. I use this this on group road bike rides and mountain bike trailsFinally Just to clarify this is designed so others can see you night or day and not a replacement for a light to view the road ahead.I loved it so much I got the matching rear light. Many of my fellow club riders have now adopted this light too.

A very bright light!
A very bright light with 4 on settings. Easy to put on bike (or in my case skateboard). The USB charging is great. I wish the battery lasted a little longer but then I just need to remember to charge when I charge my skateboard. Very pleased even at the price.

Great affordable lights
These are really excellent lights to be seen by others on the road; reasonably priced yet easy to fit (mostly) and simple to use. However, do not be fooled, these are not really suitable to ride country roads at a good speed and to be sure to see potholes and other problems. But, the these are very good at what they are intended for.

super
These are - frankly, excellent. They are super-bright, charge quickly and are elegant on your winter trainer. I reckon they last about 90 minutes from fully charged, which makes them great to use for an early morning ride at the weekend in the winter.
