This was an awesome purchase. When compared to my old lght, this is far far better with its 900lumens and gives great visibility during early morning and late night rides.
I will definitely suggest this one to everyone who rides early morning or late night alone.
Only issue is that, this interferes with my Sigma 16.16 STS CAD cycling computer. Based on some of the online forums feedback, looks like this issue was confirmed by lot of riders.
However this issue won't be there who has a ANT+/BLE/GPS based cycling computer. So please confirm this before you buy this one.
