### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Long lasting
  

*by J***. on Reviewed in the United States on May 6, 2024*

We use these for about 1.5 hours each night. They hold up well.

    Cool Product!
  

*by P***O on Reviewed in the United States on February 25, 2019*

I'd say about 80% of the time I forget to turn on my rear tail light when going on a bike ride.  I often forget to turn it off too until I'm home.  This product solves both of those issues.Came in a nice package and looks to be built well.  I tested out the stop-start lights by hand and it does appear to work well with little motion as described.I'm leaving it 4 stars for now for two reasons.1. It didn't come with instructions.  Granted it is pretty simple to operate but a little mini page or two guide would be beneficial for people like me that may accidentally break a product while unattaching it from the seat connector to the clip.  That didn't happen, the plastic is very sturdy.2. I haven't used it out on the road yet.  If my friends say it works well behind me definitely will come back and give it 5 stars.Rechargeable for 90 hours is a lot of seat time too and no battery needed!  Another nice feature.

    Our new "go to" tail light
  

*by S***D on Reviewed in the United States on November 12, 2020*

After trying this light and others, we have decided this is the best light for us.  It is easy to put on and has a variety of light patterns.  The brake light feature is awesome and it's auto shut off is very helpful.  It's not the brightest light out there, but does the trick.
