5 of 5 Great light May 13, 2020
Reviewer: Rob from NY  
Works great as a marker light for the back of my head lamp.  Also a nice task light or backup headlamp.

5 of 5 Perfect for bike rides December 7, 2019
Reviewer: Anonymous Person from L United States  
I have always preferred a headlamp to a light mounted on my bike. But rear lights were always to heavy on the back of my head but this is so small I don’t even notice it.

4 of 5 Great for it's intended purpose July 24, 2019
Reviewer: Nick Miller from BarneBarnet, VTt, VT United States  
I walk on public roads after dark a lot. I purchased 2 of these so far as compliments to headlamps clipped to the rear and used as flashing red visibility lights.

I've had no issues.

I was happy with the speed of shipping. No reason to use amazon (I look for any opportunity not to).

3 of 5 Cool light but May 18, 2019
Reviewer: H C from ajax, ON Canada  
I was super excited for this product came fast about a week or so I’m in Ajax Ontario.

I took out of the package great looking. Wore it as soon I got. A day later I used it had no issues I was in a tight spot and need the light went all day with it. Came to the end of the day the clip broke.

3 of 5 The simple edition leaves more to be desired. March 21, 2019
Reviewer: Will Huang from Vancouver, BC Canada  
- The power button is located at the front, making it easily accessible.
- A wide variety of modes for different situations. The red light signal brings attention, and the white light helps with hands-free illumination.
- Light weight.
- Rechargeable.

- The clip is hard to attach to the body without the headband. The clip's opening is small and thin, making it difficult to attach the lamp to the body, such as on the collar or on the waist belt. It would have been much easier if the lamp uses a spring clip (similar to those found on MP3 players), a safety pin or something else.
- One-button operation can also be inconvenient sometimes. Shifting through the different modes within a short 3-second interval can be confusing and requires deeper familiarity with how the product operates.

The product would have been fine as a headlamp, but for direct body attachment it leaves much to be desired.
