Review on Gunmetal K-Edge NiteRider Light Adapter - One Size by Jonathan Fernandez

Probably won't use an adapter. It works well. However, the NiteRider I use with this adapter is USB powered. As a result, I had to unscrew the adapter from the phone mount every time I needed to charge it. So it's likely to only use the mount that comes with the flashlight. If this mount had a quick release like the mount that comes with the flashlight that would be great. EDIT: In the last two months of cycling I decided to use an adapter and mount it to the quadlock phone mount on my bike. Works very well. I decided to just leave the USB charger in the pantry where I park my bike and charge my NiteRider when needed.
