    Great item & customer service
  

*by I***R on Reviewed in the United Kingdom on 6 May 2020*

Great shape, look and functions. Sensor working good too. When slow down/breaking it goes brighter. My version goes under saddle only. I couldn't mount it on post so contacted seller to ask for attachment to do so.they  sent me another version off charge so I could put it on seat post. Amazing customer service. So is the item. Bright. Visible. Adds a lot to overal look of the bike.!!

    Nice but not perfect .
  

*by G***. on Reviewed in the United Kingdom on 28 October 2020*

Nice little light, pretty good but the only couple of things I have issue is the way you need to screw it as not really smooth and also in few occasions switches itself off for no reason and for sure battery was fully charged.
